The log is normal now, there has only been a communication problem, but has recovered normally.

On awakening, is quite random. Since I started to test the 19.3, I have not suffered it within 24 hours, and when he had about 30 hours, began to occur continuously (which coincided with the battery is depleted on the dock, but I can not say the relationship). Now I have 45 hours (battery dock at 0% and 50% tablet) and is not happening.

Indeed, 45 of which 36 hours in deep sleep, on a single charge (tablet + dock) and I have remaining 50% of the tablet battery.
[Eee Pad Transformer Android Development] zdalin2003:
My tablet does go into deep sleep when it's charging (i can see it in cpu spy).

SOD only happened once when i was on 19.2, and once again on 19.3.

I also tested 17c through 18e, all of them gave me more frequent SODs. 18b was the worst for me.

19.2 seemed to be the most stable one. I just changed it when you updated to 19.3 because i got one SOD. The circumstances were the same. It was docked, not charging and with microsd inside.

On all of them i got random wakeups, but only when docked.

Could it happen when dock battery goes flat?
[Eee Pad Transformer Android Development] guevor:
Yes, I have only seen when you're using the dock, the tablet is awakened by any interrupt (normal, like wifi, an alarm, etc. ..), remains normal (screen off) and then, a seconds after, the awake process was initiated, lighting display, etc ...

I have to check further, revise logcat, dmesg, etc.. to look for a pattern, but is likely to be at rom level and not kernel.

About the deep sleep while charging, never happened to me, would be nice to have the kernel log when it happens, may be I get some clue about some other problem.
[Eee Pad Transformer Android Development] bsoplinger:
Will you move to the new .24 kernel once Asus releases source? For that matter, how long does it take them to update the source releases once they've done an update in the past?

Dock Drain is back

Went from 1.0.4 + 17c to 1.1.2 + 19.3 last night. No SoD or RR, but dock battery drained 20% overnight - it only managed 18 mins of deep sleep with 9h 23 min at 312 MHz.

So how do I check what is causing it to stop going to deep sleep again? I saw a method in here somewhere, can't find it :(

Going to try 19.4 now, see how it runs today. If I get the same drain I will go back to 17c and see if that is still good with 1.1.2...
[Eee Pad Transformer Android Development] sidneyk:
Mine never deep-sleeps while plugged into the AC charger. I think I read several posts somewhere indicating that this was by design from Asus. If you have been on and off of charger without a reboot then, of course, cpuspy shows the cumulative activity, including deep-sleep, since the last reboot or the last time you reset the timers in cpuspy.
[Eee Pad Transformer Android Development] woti23:
i have 1.1.2 and had the battery drain with 19.3 too and almost no deep sleep, i don't think its app related.

switched back to 17c and it deep sleeps normal now and used only 1% battery in 8 hours.
[Eee Pad Transformer Android Development] guevor:
Some posts back, I posted a V19.4 with a fix.

Now I uploaded to the front page.
[Eee Pad Transformer Android Development] woti23:
yes i saw it, megatron version for 19.4 is also available allready, will try over night

thanks
[Eee Pad Transformer Android Development] akyboy:
Well,.. im not going to test no more new kernels until i see at least 20 satisfied users.

19.3 was fine during the day yesterday, i docked tablet before going to bed, and this morning was HOOOOOOOOOT - i keep it in the pouch.

Not to take any more risks or damage something, i flashed 17c back.

Just heads up.
[Eee Pad Transformer Android Development] guevor:
Sorry, but unfortunately there are bugs, and while I test the kernels before publication (with and without dock ), not everyone works the same. In this case I had already used a whole day and night without problems before publish it. In fact they are already 54 hours I've been without problems.
[Eee Pad Transformer Android Development] akyboy:
No probs at all,... just wanted to share what happened.

Also,.. dock battery was around 45%, tablet was 99%,.... this morning dock was 3%,.... so probably deep-sleep problem which is i hope fixed in 19.4
[Eee Pad Transformer Android Development] thepatman:
19.4 seems to be good so far, dock battery holding up well - fingers crossed!
[Eee Pad Transformer Android Development] marcmarshall:
Noticed 19.3 was yesterday so flashed it. I got random screen wakes with it so I flashed back to 19.2. Now I see 19.4 is up!
[Eee Pad Transformer Android Development] pyro254750:
Saw random screen wakes with 19.3 and CPU spy showed little to no deep sleep. With 19.4 deep sleep is working correctly again and screen wakes are gone. Battery seems to be draining a bit faster than normal, but ill know for sure tomorrow. Additionally, 19.3 and 19.4 are the first ones I've used since 17c that did nor have sod issue.

tf101 megatron 1.1.3 guevor 19.4
[Eee Pad Transformer Android Development] marcmarshall:
Noticed a screen wake from sleep with 19.4 Going back to 19.2 to see how that is.
[Eee Pad Transformer Android Development] laslow:
Sorry for the late reply - I did try the megatron specific one, with the same result. Forgot to grab the dmesg output though - I'll load it up again and grab the log dump then post it a little later.

Won't Wake

Hi,

I’ve tested the following Kernels with the same result on all: 17b, 17c, 19.2, 19.3, 19.4

Result: When its awake I can OC to 1600 and while its wake I can’t get it to lock up, which is good. However, when setting the device to sleep it or it goes to sleep itself will not wake up after say 3mins. Once it has failed to wake up it will still do so even if I set the clock back to 1000. It should also be noted that if I install a kernel and leave it at the default 1000 it will wake up from sleep fine. As per below I have tested this docked and undocked and at a min overclock of 1200.

Any ideas why this is happening. I can’t seem to see anyone else with this issue.

Rom: ARHD 3.2.2

MicroSD: Always in

Docking: Tested docked and undocked

Model: TF101G C30 series

SIM Card: none

Thanks

Juan
[Eee Pad Transformer Android Development] taptotap:
i noticed a faster battery drain as well so far... no sod though.... :)
[Eee Pad Transformer Android Development] Lakitu7:
I've been on Kernel 17 for 18 days before I got my very first hang. This is still fabulous work and I don't even care about that one hang. You've been working tirelessly around here, and I thank you for all that you do. Sent a small donation for your time. Congrats on succeeding where Asus has not.

Rooted stock, no dock, SD card in constantly.
[Eee Pad Transformer Android Development] :
Flash ALL the kernels!
[Eee Pad Transformer Android Development] devilpera64:
Guevor very stable this last version 19.4 :-) i notice a little speed-up, but maybe it's only my brain's illusion :D however good deep sleep, very good the battery drain side, and now i hope that problem is solved for concentrate on performance :D
[Eee Pad Transformer Android Development] Nebucatnetzer:
I got an SOD with 19.4

megatron 1.1.3

No dock

Micro SD
[Eee Pad Transformer Android Development] kokopopz:
Report on v19.4.

Uptime: 37:30 hours with 32:25 sleep. No RR or SOD. Battery usage seems normal.

TF101, Revoler RC2, 32GB mSD inserted, sometime undocked but most of the time is docked. Security: PIN.
[Eee Pad Transformer Android Development] guevor:
I have not changed anything related to 3G so it's the same as 19.3.
[Eee Pad Transformer Android Development] cimbike:
Just flashed 19.4. See how it goes.

Thanks so much.

[Eee Pad Transformer Android Development] sidneyk:
19.4 seems good

So far 35:43 hours uptime with 24:48 hours in deep sleep with RRs or SODs. GPS works well, wifi works well. Overall, seems pretty solid on my tab (see signature).
[Eee Pad Transformer Android Development] guevor:
I've been 80 hours with 19.3. I did not changed to 19.4 because the change I made was minimal and I have not needed it.

The problem I am having after so many hours (and heavy usage) is the fragmentation of the ram.

This causes things like closing gmail, disappearance of launcher icons, close applications, etc. ..

In case anyone don't know what it is, I will try to explain quickly.

Kernel free memory is divided into blocks. At first when empty, few large blocks.

As time passes and the use of programs, small blocks are used and released many times.

This makes the free space (even if we have the same total free space) was composed of many small blocks, rather than few large ones.

The problem of the programs force close, etc. .. arises when you need to use a block (in our case the problem always comes up to ask 64Kb blocks), and none is free of that size, just a lot of smaller sizes. This produces a failure and subsequent closure.

Now I will test a new version with a change to try to avoid such fragmentation plus new compilation options to see if performance improves.

If it is fairly stable will upload it as V20 so it can be tested in more depth, but as always, considering that can return instability.
[Eee Pad Transformer Android Development] stcanard:
After 120 hours / 60 deep sleep on 17c with no RR/SOD I'm convinced my transformer is stable under that configuration.

I've installed 19.4 now to see how it fares in comparison.
[Eee Pad Transformer Android Development] guevor:
If someone wants to go testing it already (I've very little tested yet).
[Eee Pad Transformer Android Development] yukonking3:
Just installed v20 will let you know how it works out.

Edit: Running V20 for about 7 hous now and everthing is running great so far. Tf101 running Revolver rc2 oced 312 min and 1.5 max ondemand govner. I have run it docked and un docked 32 gig microsd installed as well as usb 32 gig inserted and 16 gig sd in dock. Deep sleep working and no lag when waking.
[Eee Pad Transformer Android Development] stcanard:
I'm downloading now, might as well go for the latest since I just changed...
[Eee Pad Transformer Android Development] xbs:
Gonna try it ASAP on Megatron.

Thanks.
[Eee Pad Transformer Android Development] miketoasty:
Just started a new setup on AOKP so might as well give v20 a try! Thanks guevor!

The source code for 9.2.1.24 has now been posted on the Asus website. Any chance the kernel will be rebased off .24?
[Eee Pad Transformer Android Development] Hammerfest:
tf101g kernel and rom source based stuff has typically been smoother and faster on my tf101

still, OP has surpased my HC pref days
[Eee Pad Transformer Android Development] farsight73:
Updated latest ICS build .24 yesterday. Now followed with flashing your V19.4 too. Look so far so good to me.. Will this V19.4 have those ram fragmentation issue as you mentioned above? What's the severity of this would effect my daily usage?
[Eee Pad Transformer Android Development] finalhit:
I believe guevor was saying that the older kernels have that problem....test20 aims to fix it.

Anyway. I just installed 20 and I think its working. I browsed tumblr with my browser to the point that crashed [tumblr has infinite loading pages...so I expect this to happen] and when it did...typically..Mathis would cause my launcher to not show icons. This time though...it didn't. It did news to redraw...which is normal...but ultimately...it was able to recover.

This is actually a bug I posted about in the apps forum. I'm glad to here you have diagnosed the problem and is working on. Thanks guevor.
[Eee Pad Transformer Android Development] stcanard:
Running for about 6 1/2 hours now, 2 observations:

- memory management is definitely causing far fewer apps to quit; I actually had to find the refresh option for CPU spy - on 17c it would have to reload every time I went to it and would refresh automatically. Now I have to trigger a refresh because it's still running

- its blazing fast. I'm reading a PDF based book through the browser on safari books online and the pages are drawing faster than a local ebook. It's noticeably better than before
[Eee Pad Transformer Android Development] carlvk:

17c was great 19.4 too, moving to 20 to test

thanks for the hard work and tenacity

Thanks to you I got my transformer back.
[Eee Pad Transformer Android Development] woti23:
in case someone wants to compare memory usage, this gives a lot of info about memory and page usage:

echo m > /proc/sysrq-trigger ; dmesg
[Eee Pad Transformer Android Development] guevor:
I just checked the latest code posted by asus and the only change I've seen is the modification/deletion of a portion of code that they added and I had already removed long ago because it caused problems.

So I do not change anything.

As a curiosity the code is to obtain information on failure with the suspension. Yes, those bugs that have long said they did not have, but have always had.
[Eee Pad Transformer Android Development] guevor:
Thank you very much for the donation. It is greatly appreciated.
[Eee Pad Transformer Android Development] kokopopz:
v19.4 is going strong. 62 hr uptime with 47 hr sleep. Going to try v20 now.
[Eee Pad Transformer Android Development] stewie01:
I've been running 17c for a few weeks on my B60 without dock. No RR and SOD. Worked perfekt for me!

Last night I changed to 20. It runs extremely fast! Browser works very smooth. Wifi is stable until now. Lets wait for the next night ;-)
[Eee Pad Transformer Android Development] marcmarshall:
Went back to version 477 (which I need to reference on post 1 of this thread to see is version 19.2). Have not noticed any random screen wakes yet and battery life with docked sleep (micro SD and dock SD installed) is good. Went from 100%/100% to 98/93 in 8 hours.
[Eee Pad Transformer Android Development] Stevemeister:
No issues yet on test 20, been running it for 6 hours now.

Reporting on V20

Thanks. Reporting on V20.

TF101, B70, Revolver 4 RC2, 216~1200 MHz, default voltages, docked, MiniSD, no SD, no USB

=> No RR, no SOD,

some random wakes

, quick WiFi reconnection on wake, deep-sleeping

One problem: WiFi cannot reconnect after returning from office to home. Need to toggle WiFi to reconnect. kmsg logs attached.
[Eee Pad Transformer Android Development] woti23:
no problems for me with v20

tf101, b60, megatron 1.1.2, dock, microsd and sd inserted, deep sleep battery about 1% for 8 hours.

no SOD, no unwanted wakeups, no problems with wifi
[Eee Pad Transformer Android Development] stewie01:
I have two Wifi Networks here at home. Just checked this problem. I have NO problem to switch from one network to the other. I can change manualy or let the pad change automaticly. Can't confirm any issue.
[Eee Pad Transformer Android Development] boonkui:
Thanks for testing the scenario. Usually my TF has no problem switching WiFi networks. Since it occurred today, I collected the kmsg logs and was hoping they might be useful for Guevor.

Running V20 on my TF-101 B50

Stock ASUS ICS 9.2.1.24

OC Settings: Min 216 GHz Max 1.2 GHz

MicroSD Card inserted

No dock

Working just fine. :)
[Eee Pad Transformer Android Development] guevor:
I looked at the logs, and the problem had already seen before. It happens sometimes (in an apparently random), it is in a bad state and can not do the scan. The solution is to disconnect/reconnect the wifi. Later I will try to review the code regarding the wifi drivers.
[Eee Pad Transformer Android Development] miketoasty:
Had the SOD after about 16 hours of the v20 kernel with a micro SD card and no keyboard dock. Other than that this kernel seems extremelyopinion in my opinion.
[Eee Pad Transformer Android Development] guevor:
At that frequency / voltage?

I put the V20 in the downloads of post #3. Still unclear if it is just as stable as V19.4, but since I already have 24 hours with it, at least not very unstable.

[Eee Pad Transformer Android Development] stcanard:
It might be a coincidence, but about 8 hours after v20 my issues started to show up again (loss of hardware function / timeouts until the system becomes unusable)

I went back to 17c and the issues continued, which fits with my experience (once they start, it's a problem until you flash a new rom)
[Eee Pad Transformer Android Development] atothis:
V20 very good and stable for me too.

16h uptime and no random wakes, dock SD always remounted when waking from deep sleep (it was an issue of 17/17c I guess), no SOD even when docked.

The only thing I noticed is about a little more dock battery drain comparing to v17.

It drained about 8% in 3 hours (tablet full, deep sleep the whole time), and about 20% in 30 minutes (tablet full, streaming video from pc).

I have not yet tested the tablet alone.
[Eee Pad Transformer Android Development] tsachi:
I've been on 17c for over two weeks with no problems (dock almost always on and micro-sd constantly in. Wifi on all day, off all night. system OC/UV at 1400, -25mA on all frequencies 1000 and up). Last couple of days I got SOD, so I'm thinking it has to do with a recent app installation rather than kernel / ROM.
[Eee Pad Transformer Android Development] stcanard:
Not for me, I've kept the apps and usage pattern very stable just for that reason.

I'm installing Revolver RC3 now, I'll put v20 back on and go for a clean/clean upgrade and see how that goes.
[Eee Pad Transformer Android Development] stewie01:
It is so silly! ONE developer here is able to produce a much more stable system than a very, very big company can do. THANK YOU SO MUCH! Good night ;-)
[Eee Pad Transformer Android Development] gkillerx:
You are so right, v20 is now very stable and good for every day use.

Lets all donate something, if we all just donate 1 euro (or more) then he can by some good sets of beers ;)

I already donated:

[Eee Pad Transformer Android Development] Stevemeister:
Just noticed a strange issue with test 20, tab wouldnt charge anymore. Gonna test V20 now to see uf it charges again :-)

Edit: Charging works as it should on V20 :-)
[Eee Pad Transformer Android Development] Nebucatnetzer:
Have you done anything specific to fix it? I'm asking because you might want to share it.

A lot of people are staying away from ICS because of this reboots.
[Eee Pad Transformer Android Development] guevor:
The test8 includes a fix for a bug that can cause stability problems, and an increase of 1.7Ghz voltage to make it more versatile. That forced to some changes on core voltages increment than I hope don't cause other problems. For me seems working good until now.

As always, I do not recommend using 1.7Ghz (too much voltage necesary and too much heat)
[Eee Pad Transformer Android Development] SWEagle:
I run several benchmarks and it is stable! :D
[Eee Pad Transformer Android Development] guevor:
The problem is that it was unpredictable and I'm not sure if was really solved or only eliminated some of its origins.

The last asus version V9.2.2.3 contains some fix, I configured the minimun frequency to 312, disabled the conservative on screen off, changed frequencies and voltages, .. who knows

Need more days to see if really works.
[Eee Pad Transformer Android Development] Nebucatnetzer:
That you have some data.

ROM: CM9 build by Ricardo

Frequency: 216- 456 Mhz while screen off.

456- 1400 Mhz while screen on.

both set on boot so I'm overwriting your settings here.

Voltages: Untouched

Governor: Interactive

Kernel version: test7

I had reboots as soon as I switched the screen off. So even when it sleeps 5 minutes it's already a huge improvement it sleep 1h though.

I'm going to test if the reboots happen with your stock settings and if I can replicate them when I flash back to the stock kernel.
[Eee Pad Transformer Android Development] strker45:
The last two kernels break wifi for me. it keeps telling me to configure ethernet connection.

im on the most recent stock version of ics btw.
[Eee Pad Transformer Android Development] devilpera64:
My Elite Tegra 2 can handle very well 1.7Ghz..i think that i'm very lucky to reach this freq without problems! Wifi works. I think that we can take a lot of points bumping memory/gpu side..i remember when Blades created a kernel under Honeycomb that generated a big improvement on GPU/memory side :-) Do you think that we can reach 8500-9000 Antutù scores with other Kernel mods in the near future? :-P
[Eee Pad Transformer Android Development] Nebucatnetzer:
Okay I did some testing.

It works as well with your stock settings. After that I reflashed the ROM and tried it again.

I switched the screen off and bamm after a few seconds it reboots.

I flashed your kernel again and the reboots were fixed. So it's definitely something in your kernel.
[Eee Pad Transformer Android Development] brando56894:
I've been having the WiFi issues also on the EOS nightlies, sometimes it works and other times it doesn't. It would work after a few reboots or a few on/off toggles. I seem to remember either in a thread for the TF or my Rezound a dev had mentioned that you had to delete a certain wifi config file for it to work, but I can't seem to find it for the life of me!

I envy you, mine can only handle 1.4 GHz, it will handle 1.5 GHz for a little while but 1.6 GHz causes instant freezes followed b a reboot.
[Eee Pad Transformer Android Development] linuques:
Very cool. What launcher is that?
[Eee Pad Transformer Android Development] seano666:
You are an animal Guevor! Thanks for continuing to update this great kernel. I'm running CM9 March29, test7 at 1.5. 12 hours now, no RR, SOD, Freeze, ANYTHING! Feels like I have a new tablet, it's so fast!

And decent battery life too.
[Eee Pad Transformer Android Development] guevor:
That looks strange. I don't know how can detect an inexistent ethernet.

I understand you do not have any hardware connected to the dock (I have seen in the screenshot that you have the dock) and you have a tf101 without 3G, etc. ..

The only thing I can think of is to send me a log just after boot to see what detects.

You can generate it by executin on a terminal:

dmesg > /sdcard/dmesg.log

On the sdcard you can get the dmesg.log file and send it to me.
