It wasn't fixed, I'm still getting SODs on Netformer 1.2. This fix was committed by Xin Xie back in March and since then we've still had SODs all over tegra 2 based devices. I'm not convinced it's that simple to fix.
[Eee Pad Transformer General] weenrock:
So it seems to be Tegra 2 processors? Not just the transformer?
[Eee Pad Transformer General] ToddW2011:
On a slight aside, what's the scale for interpreting the battery temp? Mine varies between 260 to 290.
[Eee Pad Transformer General] Roach2010:
260 = 26.0 degs C

290 = 29.0 degs C
[Eee Pad Transformer General] fatbas202:
Hell yeah. Glad to see you over in these forums as well. You've done wonders in the dev community on the Captivate and I really look forward to seeing what you can do with the Transformer!!!!
[Eee Pad Transformer General] EP2008:
I've had the SOD problem on both Archos and coby tablets. This isn't a tegra, transformer or honeycomb issue.
[Eee Pad Transformer General] freeza:
That leaves USER issue. Thank me later.
[Eee Pad Transformer General] EP2008:
Or problem apps or conflicting hardware. My sod rates went up considerably after attaching the keyboard dock.
[Eee Pad Transformer General] mrgilmorean:
You are assuming that the cause of the SOD is common between all three which seems highly unlikely, given the vast differences between the tablets. I don't know how pervasive the problem actually is but it seems that a significant proportion of people are affected. That seems to point to some sort of inherent design flaw, either in software or hardware. I am surprised none of the review units that went out had this issue.

Unless you are joking which means I've got egg on my face.
[Eee Pad Transformer General] EP2008:
No, I didn't say the cause of SOD is common, I'm suggesting that sod is common. I wish I knew the cause.

Sent from the Acer A500 while my Transformer gets fixed :(
[Eee Pad Transformer General] Igor02:
When i got my Transformer (on Friday) I had many SoDs with the stock-firmware (.13). When I updated to Prime 1.3 I also got many SoDs (with or w/ Netformer kernel).

But now I am on Modacos Rom with Netformer 1.2 and I didnt have an SoD in 3 Days! *knocking on wood* :D
[Eee Pad Transformer General] lyzanxia:
Yep, since netformer 1.2 kernel, I had no more SOD
[Eee Pad Transformer General] smudger1000:
Asus replied to my request that i sent in the other day and told me to factory reset and then apply any updates available. I held off posting here for a week to make sure but so far i have not had a single SoD. May not be helpful to all but thought I would let you all know.
[Eee Pad Transformer General] spuniun:
Poking around I discovered this about the so-called SoD

Based on battery usage overnight, its clear that the system effectively stopped logging all activity but power continued to be consumed.

This was on PRIME 1.3r2 with netformer 1.2. No ramdump so I'm assuming it's not a kernel panic.
[Eee Pad Transformer General] boqonx:
I wiped /cache and /data after having so many SOD issues, and right now I'm rock stable at 1.2GHz w/o any single SOD for the past 6 hrs! Crossing fingers :P
[Eee Pad Transformer General] mystombox:
can anyone try this out and confirm?
[Eee Pad Transformer General] spuniun:
Considering the high number of people running unrooted stock that still have this issue I'm pretty sure this is going to be no help.
[Eee Pad Transformer General] weenrock:
I did a factory reset, problems seem to be consistent and I still have the random resets.

I am actually debating if sending it in will help... at all.
[Eee Pad Transformer General] XsceneXhippieX:
i got my tf in the mail yesterday, and had a sleep of death within the first 30 minutes of usage, no root, no exploits, running completely stock firmware. i then charged the tablet and did the ota update provided, and then again about an hour after the update i got another sleep of death. the difference between the two was before the ota update the SoD forced me to reboot, and after it just took wayyyy too long to get to the lock screen. just posting this as clarification of the SoD's not being caused by rooting, custom kernels, or custom roms becasue i am still completely stock (in hopes of a 3.1 ota :P) and i am still getting this issue, i thought my power button was on the fritz already but apparently others are experiencing this as well and that makes me feel better about my new AMAZING tablet, im itching every minute to root it though lol i wish there was a way to root and still successfully install ota updates without and adjustments

but 13 hours since my 2nd and last SoD and no issues so far, just the initial 2
[Eee Pad Transformer General] spuniun:
Been using netformer 1.3 kernel for about 24 hours and I did not get my customary over-night SoD. Keeping my fingers crossed that netarchy figured the issue out.
[Eee Pad Transformer General] armstrom:
Just to add another datapoint. I've had my transformer for a week now and have not had a single SOD. I leave the tablet on all the time. I last charged the device was 42 hours ago and my battery is currently at 48%. My tablet arrived with 3.0 and I immediately updated to 3.0.1 (x511 build) OTA. I have not rooted and do not use keyboard dock. I leave my wifi on all the time.
[Eee Pad Transformer General] jcarrz1:
So. When I do get my transformer, i want to know if I should charge it all the way before using it.

That screenshot above with a 15% straight drop in battery without usage over an instant period of time gives me doubts about battery stability in the software.

Is is best to make the first boot with the battery all the way charged?

how does the transformer come charged? half? none?

thanks for your thoughts.
[Eee Pad Transformer General] spuniun:
That 15% drop is an indication of a SOD - nothing to do with the battery stability or charge methods.
[Eee Pad Transformer General] smudger1000:
Bad news after a factory reset and just over a week of no SoD just had one I have contacted asus again I shall wait for a reply
[Eee Pad Transformer General] lostsoulktash:
I've had my transformer for about 2 weeks and have installed prime r2 and overclocked with no SoD, even on stock it was clean.
[Eee Pad Transformer General] stikllr04:
SOD issue

I've factory reset, had wifi on and off, removed every single widget, auto dim off, i've tried pretty much everything. I've had my Transformer for 5 hours now and I'm pretty pissed off. I get the SOD every single time....yes every time. I can't shut the screen off with out it getting stuck. It also takes a few tries to restart someimtes. I even tried taking screen lock off, I've tried absolutely everything. I've waited so long and I loved this tablet it was great for the 1st hour! I called Asus and they told me they couldn't replace it, I had to send it in, and they would only pay for delivery one way. WTF asus are you kidding me right now.
[Eee Pad Transformer General] mystombox:
Have you tried doing a factory reset and not installing anything.

See if SoD comes back with a fresh set.

It may be due to some apps running?
[Eee Pad Transformer General] glitterballs:
Can [edit - rooted] users having problems resuming from suspend (I refuse to call it what you all have been calling it :) ) post the output, if any, from, (this should be done from an adb shell):

dmesg | grep failed | grep voltage

Anyone having this problem frequently, maybe you want to install the terminal emulator app from the market and log the output of dmesg to your sd card by doing the following (this will continually log the kernel messages to the file asus-fail.txt on your EXTERNAL sd card, so if you don't have an external SD card, this won't work. (You can do it to your internal, this is just the way I've done it):

cat /proc/kmsg > /data/Removable/MicroSD/asus-fail.txt

and then pastebin asus-fail.txt and send me a link. Again, this second thing, only users having frequent issues with it, please do this. Otherwise you'll be posting huge dmesg outputs with no really good info for me.

What I think is happening is that the regulator goes to switch the CPU frequency to, let's say 816MHz but fails to set the voltage for it, so it's almost as if you're drastically undervolting your CPU. It doesn't shut down and it doesn't panic, but it continues to use battery which is why people see large drops in battery life after doing a hard reset.
[Eee Pad Transformer General] naz78:
Thanks for trying to help.

I installed terminal from the market and I tried typing in the following but I got permission denied:

cat /kmsg > /data/Removable/MicroSD/asus-fail.t
[Eee Pad Transformer General] glitterballs:
You need root. I'm just so used to having it on my machines, I forget some people don't have it.

Also, don't forget /proc in front of kmsg.

And for anyone who is wondering, I did catch this happening, but I'm certain I use a different governor/settings than probably everyone, I just want to see how common it is on the stock governor (Interactive?)
[Eee Pad Transformer General] jcarrz1:
yea, this cpu thing seems likely.

can someone inform me what governors the new kernels these days for transformer have, i think theres 2, one by netarchy? and one by something with a B

do they have smartass, or others?

this could be the culprit.

also, maybe ASUS has diagnostic skills and has figured it out in time for the 3.1 update. that'd be cool as well. It's possible that select Tegra chips can handle undervolting easier than others, and that's why some people NEVER see the SOD, others see it all the time, and some people only see it occasionally.
[Eee Pad Transformer General] mr.BeBoT:
I was hoping I'd never have to post here.

After 2 solid weeks of use, I finally got the SOD. I've been using Prime! since opening the box and Netformer since initial release.

The only thing I did yesterday was install aldiko free. At first I got FCs just trying to start the program, then FCs when opening included books. While going online to research the cause (< 5 mins) I found myself with the SOD. I promptly uninstalled aldiko thinking it was the culprit as I have not installed anything else for the last 3 days. After 20 mins, 2 complete lockups with the screen on and stuck.

I promptly did a factory reset, and no problems again since (15+ hours.) I'm reluctant to install aldiko again but I may have to for confirmation/consistency.

16GB / Prime! 1.3r2 / Netformer 1.3 / SetCPU 1.2 Interactive
[Eee Pad Transformer General] K900:
Still didn't get my transformer yet... So I might be wrong, but anyway, try the following:

while true; do cat /proc/kmsg > /sdcard/kmsg.txt; sleep 5; done

Then, when you get a SoD, remove the external sdcard and post kmsg.txt here.
[Eee Pad Transformer General] glitterballs:
Yeah, actually I do want a full dmesg output for people who are having it frequently, or for anyone to paste the dmesg output from the double grep command I posted yesterday. What you posted would overwrite kmsg.txt every five seconds, and it may be that a failure to set the voltage won't necessarily freeze the system. I caught a failure to set the voltage once randomly in dmesg while I was looking at some other things, and I just want to see how common it is on either stock rooted kernels or any of the custom kernels here. I fixed something similar on Captivate froyo, but it was easier because my phone was one of the few affected. I have a couple theories on this, but so far I haven't had it happen, and I haven't gotten any feedback on this, so without anything from dmesg and without being able to reproduce it, there isn't much I can do.
[Eee Pad Transformer General] K900:
It won't. /proc/kmsg doesn't contain EOF, so in theory it should be just writing and writing all the time. The loop is there just in case something crashes really ;)

By the way, can anyone try decompiling the framework? It probably does change something when screen is locked.
[Eee Pad Transformer General] trailblazer2002:
glitterballs, if you are right about the cause of this problem, is that fixable by software? Or is it a hardware problem? This problem is very annoying on my 32GB Transformer. I get the SOD almost everytime the tablet goes to extended sleep if it is not plugged in to the charger. And I have never seen it when it is plugged in. I am on the verge of returning it. It hard to explain to my wife that if she tries to use it and it does not power on, to hold the power button for about 15 seconds, then release it, then press it ...

Very frustrating.
[Eee Pad Transformer General] jcarrz1:
has anyone had this with 3.1?
[Eee Pad Transformer General] finalhit:
yup, i've had it happen in 3.1

my situation, (i think) is interesting. i've never had SODs until about yesterday. i was in 3.0.1, and everything was fine. then, when i was trying to play plants vs zombies, it kept crashing on me, and i then realized it was due to my save file was corrupted (i can play the game fine with a new profile).

then later that day (yesterday) i got a SOD. then i got more SODs. then i upgraded to 3.1, and still, more SODs. i've had about 10+ SODS between today and yesterday, I've never had them before (actually, maybe once or twice, since i've had the device...which is around 3 weeks). i thought i was one of the lucky onces up until yesterday, and it just happens way too often now.

i haven't read the entire thread, since up until yesterday, i looked down on you lowly peasants :P. so anyway, have you guys ruled out file system corruption? maybe it happens when the system tries to access a corrupted sector of the disk?

I don't need a signature.
[Eee Pad Transformer General] Reverence12389:
In the first three or four weeks I owned the Transformer I had the SOD happen once MAYBE twice. However, the last two or three days it has been even more frequent...pretty much when the tablet lies idle for even an hour or two. It has happened about 6 times and it is getting very frustrating. I opened up a support ticket for Asus, let's see what they say.
[Eee Pad Transformer General] glitterballs:
Well...if i'm right, it should be totally fixable with software...probably just a couple lines of code. Ultimately a hardware QC issue, but fixable. Still, I'm pretty much working blind here since I'm not affected and I haven't been given any feedback...I guess no one is having this problem anymore otherwise people would've posted some dmesg output right?
[Eee Pad Transformer General] K900:
I'll get my TF in some two weeks :( Slow shipping is slow.
[Eee Pad Transformer General] netarchy:
Too low voltage during sleep for affected units perhaps? ;D
[Eee Pad Transformer General] K900:
I thought the same when I saw it happen on my friend's device. Couldn't get anything out of it though, didn't have my laptop with me.
[Eee Pad Transformer General] glitterballs:
Yeah, something like that.

So, I actually did catch the regulator failing to set the voltage once in dmesg. For some transitions on the way up the CPU should be ok slightly undervolted, that is, if the original step is close enough in voltage to the requested step. If it happens during transitions on the way down, the CPU will be overvolted, but wouldn't (I think) cause a hang. Kinda what I'm thinking is that there aren't any checks done to see if the voltage is set correctly or not before changing the CPU freq. If this isn't the case it would be simple enough to hold at the current frequency for one more sampling_rate interval and go from there.

I wanted to take a took at the regulator and clock code, but holy hell have you ever tried to browse github on the transformer?! Just an awful awful thing to try to do.

Maybe people would take my posts more seriously if I didn't joke about being on unrooted stock Eclair...:D
[Eee Pad Transformer General] trailblazer2002:
My Transformer locks up every time it goes into sleep for more than an hour. Everytime. However, if it is plugged it to the charger, it never locks up. I would try to capture the file you need, but I am not rooted. I can root it, but at this point, my wife is frustrated with it so I am considering sending it back. However, if a solution could be found I would keep it. This tablet is great otherwise.
[Eee Pad Transformer General] glitterballs:
Of course, I could be completely wrong about all that. I was kinda hoping I'd have a little more to work with by today but ...meh. It does seem like if there was a QC issue with the rails used to set the voltage, and no checks being done on whether or not the voltage was set correctly, it would explain why some people have this happening much more frequently than others.
[Eee Pad Transformer General] glitterballs:
No worries mate. There's enough people around here rooted as it is, you'd think we'd be able to get the info we need. The plugged / not plugged thing might turn out to be interesting, and at least will give me something to think about during the drive back home. :) And it's also about 100% more info than I've received from anyone else. You may want to return/exchange it as it does seem to be partially a hardware defect....just basing that on how some people don't seem to have this issue at all (me), and others are. And if it gets SWMBO off your back at the same time, well... win win right? :D

Also, user since 2008 and two posts? Someone give this guy a medal!
[Eee Pad Transformer General] worminater:
I was hoping 3.1 would fix it :(
[Eee Pad Transformer General] Reverence12389:
That is what I am hoping too. Mine has been shutting down constantly recently and if 3.1 doesn't fix it then I plan on *****ing at Asus until I get my money back.
[Eee Pad Transformer General] XmemphistoX:
Not sure if this is what you consider the sleep of death. Sometimes when i am using my tablet, the screen will shut off and have a high pitched tone from the screen. Ill press the power button and unlock only to have it go black and have that high pitched noise again.

This can go on for around 5 times before the screen stays on. Really annoying, anyone having similar issues?
[Eee Pad Transformer General] N23:
I had a Black-Screen-Of-Death too today, with 3.1!

What i recognized was that the screen itself was not black, just the backlight stays off! When i pressed the power button it sometimes flickered a little bit...

when i used a bright flashlight i could see the screen and unlock my unit - i fixed it when i lower my screen brightness settings (and switchted the unit off and on with a short press of the power button).

immediately when i raised the brightness to high the backlight died again, also with auto brightness and a bright environment it died!

so look if just the backlight is off - use a really bright flashlight, then the ips is a little bit transflective!
[Eee Pad Transformer General] vincheesel:
Transformer was SOD'ing since I got it, every night! (except when on charge)

tried .13, still SOD'd, I decided to root it (switched back to .9) and decided to do a factory clean install with Prime 1.3r2. then I updated to 3.1. (manually) been running a few days without an SOD. I left the settings on stock (except I activated auto brightness)

Hope this helps guys

I have the TW version.
[Eee Pad Transformer General] Reverence12389:
I was having the problem over the last three days when I had automatic brightness on, but once I turned it off, I haven't gotten the SOD.
[Eee Pad Transformer General] K900:
Hm. brightness > voltage to the backlight LEDs > total voltage > undervolt > SOD is probably the way brightness thing works. Do you have it set to max (or some high value)?
[Eee Pad Transformer General] N23:
my backlight dies at max settings...

and you can't dim leds trough the voltage, you need to use pwm!
[Eee Pad Transformer General] diomark:
Any progress on this?

My transformer dies almost every time if I leave it in the keyboard dock for more then ~30 minutes.. requiring a hold the power button / restart..

-mark
[Eee Pad Transformer General] hauj0bb:
Ugh, it saddens me to see this thread, as I just ordered a Transformer today. I own a Captivate as well, which has been replaced 3 times due to random SOD's.

It seems like some aren't experiencing this issue, which leaves me to believe that it's probably hardware related. I hope I luck out with a good device.

Edit: There's an app called "Captivate Keep Alive" in the market that I used to prevent the device from going into deep sleep, it may work for the Transformer as well.
[Eee Pad Transformer General] glitterballs:
Over a week ago I posted instructions for users to log dmesg output, so far there has been exactly zero response. If you want to see some progress, start logging dmesg and let us know.

Using what kernel? edit - PM me, don't get this further off topic with completely unrelevant info. I've had fixes for i9000/reoriented OC'ed kernels since like Christmas. Non OC'ed reoriented ones never had the problem afaik, and I'd really be surprised if Samsung didn't have this fixed by the time froyo for Cap. was 'officially' released.

Can we get some freaking moderation in this forum to move threads to the correct forum? Including, maybe, even this one as there's no development related info here, and apparently no other interest in making it development related.
[Eee Pad Transformer General] Kid Poker:
Damn I'm having 2nd thoughts about it, just ordered one, and should be coming in the mail soon, thinking if I should return it already and not have that hassle
[Eee Pad Transformer General] K900:
Don't worry. First thing, not everyone is affected. In fact, most people aren't. Secondly, once I get my hands on an affected device (or someone else skilled enough to provide the logs), we'll get this sorted out in no time, cause the most probable solution is just a small patch to the kernel source.
[Eee Pad Transformer General] mrgilmorean:
My transformer has not had a single sod since I updated to 3.1 ten days ago. My machine used to sod at least once a day before that. Not saying 3.1 has fixed everything for everyone but it seems to have fixed mine.

Crossing my fingers that the situation remains this way.
[Eee Pad Transformer General] daffyduck2602:
Same with me, no problems since I rooted and moved to 3.1, with pattern screenlock enabled.
[Eee Pad Transformer General] EP2008:
No SOD after 3.1 upgrade either off battery or on the charger - on the dock or off... :)
[Eee Pad Transformer General] dfin13:
No Sleep of Death since 3.1 for me either. It went away for a week or so prior, and then it was happening a couple of times a day until 3.1. After the update, none of that nonsense, so hopefully whatever it was has been fixed.
[Eee Pad Transformer General] trailblazer2002:
Same here. I was having the SOD about 2 or 3 times a day. But after the 3.1 update (5 days), I have not had a single occurrence. I have the perfect Transformer. But wait, that is too good to be true. After having the Transformer for almost 3 weeks (I bought the 32GB version), I checked the storage menu, and it is a 16GB version. Even though the box said 32GB. So now I have to return the perfect Transformer :(.

Not happy. I hope I get a replacement as good as the one I am sending back
[Eee Pad Transformer General] lifeisfun:
I'm having hard time to wake up my Transformer every time when the screen blanks.

Very annoying. I have to either push the power button several times and if that doesn't

work then plug and unplug the charging cable. When docked, no problems.

What to do? :confused:
[Eee Pad Transformer General] EP2008:
Well... I got my first SOD with the 3.1 update. Had gone to bed around midnight and in the morning the device was off. Checked my battery monitor app and the data was cut off around 2:30am, so 2.5 hours it was put on standby, it went into a SOD :(
[Eee Pad Transformer General] lvlolvlo:
No issues here either after updating to 3.1
[Eee Pad Transformer General] lifeisfun:
I just did factory reset and the problem persists, drives me crazy

since my wife's Transformer doesn't have this problem ( 2 weeks older then mine)

both updated to 3.1
[Eee Pad Transformer General] lifeisfun:
Does it wake up if you connect charger ?
[Eee Pad Transformer General] EP2008:
It was on the dock with a charger plugged in. Just like I do every night... I hate the Randomness of this because my routine doesn't change and night and I use the same apps before I go to bed, yet one day is good and one day SOD.
