[Samsung Galaxy Tab Plus] garyd9:
If all the memory card SOD's are from sandisk class2 microSD's, it tells me something. On the other hand, if some users with sandisk cards (even if they are also class 2) don't have SOD's, it doesn't tell me anything.

For example, there might have been a bad batch of sandisk sd card controllers used on class 2 cards that don't respond well to suspend commands. Not every class2 sandisk will have one of those controllers.

There are two users who are both using that class/brand of card who ARE having the problem, which gives me some direction to look in. I just feel very bad asking (begging) those two users to purposely use those cards knowing it can cause SOD's just so I can get some "post-mortem" type info.

(On the other hand, if the issue is isolated to only those cards, those users would probably be happy that their tablets aren't broken.)
[Samsung Galaxy Tab Plus] ringnutz:
Yeah, I hear you. If I get any sod's I will be sure to report them.
[Samsung Galaxy Tab Plus] GTOJim:
I have been having SOD issues. I'm using a Scandisk 16GB class 4. I will remove it and report back.

I went a few days with out problem using the Auto Airplane Mode app but yesterday morning the battery was dead. Had a 70% charge when I went to bed.

SOD's happened often prior to using Auto Airplane Mode I'm going the disable or uninstall the app, remove the scandisk chip and see how things go.

Thanks to Gary for trying to get to the bottom of this problem.
[Samsung Galaxy Tab Plus] garyd9:
Once I get a /proc/last_kmsg that shows the SOD, I might have a kernel for that person to try to see if it makes the problem go away. Just some very minor tweaks, but they might help (unless the last_kmsg shows something I'm not expecting.)

FYI, if you get the SOD, press/hold the power button to force the tablet to reboot. As soon as the screen even flickers, let go of the power button! (If it reboots twice, the last_kmsg data will be overwritten.)

On the off chance that there is no /proc/last_kmsg, I'll need the output of "dmesg" generated very soon after a reboot. I'd suggest installing a free utility from android market called "OS Monitor." Don't bother with the tablet verison (it keeps FC'ing on me) - just get the normal version.

With that OS Monitor installed, you can save a copy of dmesg quickly: Start it, tap the last tab (Message), tap the menu button (button of the screen), choose "export log", and type in any filename (don't spend a lot of time with the name. It can be just "aaa.") That will put a copy of the dmesg in the tablet's internal sdcard (/sdcard) with whatever name you specified... you can pull it off or whatever.

Actually, might as well generate the dmesg FIRST, and then check for /proc/last_kmsg. The reason is that the dmesg is a fixed size, and if lots of kernel messages are getting generated, the info I need will disappear...

Thanks

Gary
[Samsung Galaxy Tab Plus] GTOJim:
Ok I installed OS monitor and will put my ScanDisk class 4 card back in the tab.

For me it seems I often have a totally dead battery in the morning, requires setting the date and time. I'll see what I can do to get the info you need. The tab requires some charging before it is able to boot.
[Samsung Galaxy Tab Plus] garyd9:
In a strange way, digging out this issue is fun. Annoying, perhaps, but still fun. ;)
[Samsung Galaxy Tab Plus] garyd9:
Are you having SOD type issues and are using the "supercharger" script?

If so, please read on..

Under NORMAL circumstances, if the kernel panics (encounters a bug it can't recover from), it will pause for 10 seconds and then reboot itself. Unless you happen to be sitting in front of the tablet when this happens, you probably would never even know about it.

However, that "supercharger" script is setting a kernel parameter that prevents the kernel from rebooting itself after a panic. Instead, the kernel is going into an infinite loop. If screen is turned off when that happens, the screen will STAY turned off. It'll show the symptoms described as a "sleep of death." The only way to break that loop is to do a "hard reset" (which is accomplished by pressing and holding the power button.)

I've PM'd the author of that script to try and find out why he's disabling the kernel panic timeout. There may be a good reason. (I'm not sure what a good reason would be for a device that has no way to indicate a panic, but I didn't author that script.)

In the meantime, if you are using that script AND experiencing the so-called SOD issue, I'd advise you to leave your tablet on a charger if it'll be left for long periods of time (more than a couple hours.) The reason is that if it's not being powered externally, that infinite loop I mentioned earlier can easily drain your battery completely (and android devices don't like having completely drained batteries.)
[Samsung Galaxy Tab Plus] tp248990:
Are you using it stock or ROM?

Ive had this issue and ive found out I had a faulty memory card. Formatting it did the trick for me for a while then it crashed again (random shutoff, stalls). I just bought a new memory card and I havent faced the problem since
[Samsung Galaxy Tab Plus] GTOJim:
Very informative reading. I'm not using supercharger on

my tablet but was thinking about trying it. I now know better and will not use it after reading Gary's great post.

Not SOD for me today, maybe tomorrow.
[Samsung Galaxy Tab Plus] zeppelinrox:
Hey nice rant LOL

1. You know that there is an unkernelize options right? Or maybe you don't know EVERYTHING... try that before the sky falls.

2. You behave as if the script is the source of every SOD in history. It doesn't even seem like many people in this thread even use it. So you're assuming alot.

Go ahead and search the 700+ page supercharger thread and you will be hard pressed to find a SOD issue reported.

3. I did take what you say under advisement as I don't claim to be infallible and I will be making a change to be on the safe side.

And that's how you get to be the best.

From listening and

never

thinking that you know everything. You should try that.

4. You act as if I was somehow rude to you or ignored you or something. Which I wasn't. Grow up ;]

5. I don't claim ownership of the tweaks, I claim ownership of the script and the names that I use.

So I guess you really don't know eveything and assume way too much.

If you don't like it, too bad because that's reality.

But maybe you're too busy drinking to escape from it.

I'm really not sure - as I don't want to assume too much, unlike some people.

---------- Post added at 08:47 PM ---------- Previous post was at 08:28 PM ----------

Oh you're NOT using it and yet you have this problem?

Thanks for proving me right and whatisname as the boy who cried wolf.
[Samsung Galaxy Tab Plus] Zadeis:
The point being in regards to the script is that the people who were using it had significantly less SOD's when they stopped using it. It didn't completely remedy the problem. That's the point garyd is making.

Either way I see it, when looking at garyd's explanation, the way you set up the panic timeout the result isn't good since it has been over ridden in a manor that isn't great. Now lets all take a breather here and fix things. I want to know why the SOD's are happening since they have happened to me multiple times. Having two devs bicker at each other isn't a good thing either.

Now I did follow gersen416's suggestion here and much to my surprise I haven't had an SOD yet. I did an Odin back to factory defaults. Set up my tablet to the point where I could use it. Now I did run into a snag when updating via kies.

The night I was doing it a new version of kies came out and I think the servers were under load so it kept timing out and I had to start over. So I then decided to update via the update feature on the tablet. Which btw took all of 10 minutes vs kies taking about 50 minutes (not sure why that's happening maybe it's just me). I then did a factory reset under settings > Privacy > Factory data reset.

Since I have done that process there (slightly different from gersen416's steps) I have not had an SOD for 5 days with keeping wifi on the entire time and using the GPS (Sygic) on a trip over the weekend.

Figured I'd get my input in and again I hope we can get along here :/

Edit:

Just to add I did root it after I updated and did the factory reset and also put garyd's custom kernal on my tab too.

Edit number 2:

To add more (more and more is coming to me as I sit here) I also have setCPU adjusting voltages as follows (did this 2 days ago) do note I don't OC up to 1400mhz.

1400mhz - 1475mv

1200mhz - 1250mv

1000mhz - 1150mv

800mhz - 1050mv

500mhz - 950mv

200mhz - 925mv
[Samsung Galaxy Tab Plus] slyd0997:
Just want to mention, I had a 7+ tablet had the SOD regularly. It was not rooted. It did have an 16g SanDisk sd card. I returned it. I've had 7+ tablet number two for about 5 weeks without any SODs but I have also been using the airplane mode app by Don with no sd card. One night I left airplane mode off and I heard it reboot for no reason.
[Samsung Galaxy Tab Plus] zeppelinrox:
Ya I understand.

My point was that I did listen to the advice so I really have no idea why he's being so pissy - especially since I had noted in my PM that unkernelizing is an easy option for the time being.

He conveniently forgot to mention that bit on his little rampage tho :rolleyes:
[Samsung Galaxy Tab Plus] jasonemorrow:
recieved my replacement tablet. Running stock with same apps as my previous one and no sod's for five days. Put in pny 32g class 10 and sod within 24 hours. If I get more I will remove it to see if they stop again. Wanted to test thouroughly while stock. Hope this helps. Thanks,

Jason
[Samsung Galaxy Tab Plus] garyd9:
Enough talk about that kiddie script. I believe the author has a thread dedicated to it elsewhere. I've made my suggestions based on what I'm seeing, and took the time to explain why I made my suggestions. More importantly, I've explained how they relate to the topic of this thread. I'm sure the author of that script would also want to keep this thread on topic. (...)

In other news...

I've posted an update to the 6210 kernel (20110123.) For those who are already using the custom kernel and are experiencing kernel crashes, please update and let me know if it helps at all.

I'll even continue to work with you if you are using something that disables kernel panic reboots (though if you are doing that, keep a power adapter nearby!)

Take care

Gary

---------- Post added at 11:53 PM ---------- Previous post was at 11:45 PM ----------

This is a dmesg log from after you rebooted from the SOD? Oh, this is a stock kernel as well...

Okay, I don't see anything unusual here. The card is recognized properly and brought up. Have you already tried formatting the PNY within this or another gt7+ tablet? That shouldn't matter, but some claim it's helped them.

(If it does matter, thats another kernel bug...)

Gary
[Samsung Galaxy Tab Plus] bdds13:
I can't test this right now (because I don't have this tablet yet) but has anyone tried using softlocker to try to prevent sod's? I have a viewsonic g tablet and some kernels cause sod's but with the softlocker app most people stop getting sods since it stops the tablet from going into deep sleep.
[Samsung Galaxy Tab Plus] zeppelinrox:
Based on what I'm seeing, I suggest to do as jasonemorrow did and get a replacement instead of playing with your kiddie kernels.

Based on what I'm seeing of course but I don't have to explain why because it's so obvious, based on what I'm seeing.
[Samsung Galaxy Tab Plus] :
Based on what Im seeing, I highly suggest that either everyone gets back on topic and stops nit-picking at every little thing, or this thread can be closed.

I vote for the first option...
[Samsung Galaxy Tab Plus] GTOJim:
Here is a file from OS monitor.

Battery was completely dead again. After 1 1/2 hours on the charger it didn't have enough charge to boot. This can't be good for the battery.

I'm a total noob at uploading files. I named the file aaa but couldn't upload without giving it an extension. So I renamed the file aaa.zip It's not really a zip file since I had to give it an extension to upload.

Hope this helps.
[Samsung Galaxy Tab Plus] garyd9:
Before the device reboots again, can you please pull off a copy of /proc/last_ksmg and upload it?

I see that the ram console was generated, and it should give insight as to what happened...

Thanks

Gary
[Samsung Galaxy Tab Plus] GTOJim:
I'm not sure what to look for in that directory. Opening the directory using root explorer it gives a list

text viewer

SQLite Database Viewer

Linux Script Handler

Test Editor

ZipViewer

TarViewer

RarViewer

Above is is listed under Internal

There are two other choices Open with General or Apps those also have lists under them.
[Samsung Galaxy Tab Plus] garyd9:
/proc/last_kmsg isn't a directory - it's a file. I need a copy of that file. Can you copy/paste the file to /mnt/sdcard and then upload it here?

Thank you

Gary
[Samsung Galaxy Tab Plus] GTOJim:
Where should this file be located? What I found sure looked like directories to me having the same names. I click on proc then it opens to a long list. Clicking on last_kmsg opens to the list in my previous post.
[Samsung Galaxy Tab Plus] garyd9:
Within the directory called /proc is a file named "last_kmsg"

I have no idea what file explorer you are using, but with most of them you can tap/hold and get options for copying, etc.

When you just tap on it, your file explorer is probably giving you options for VIEWING that file (which isn't what you want.) Being the file has no extension, it doesn't know what type of program to use to view it, so it's giving many choices. If you were to do that and choose "text viewer", you'd like see what looks similar to the kernel log you posted earlier.
[Samsung Galaxy Tab Plus] GTOJim:
Ok understand. I'm waiting for my tab, I was trying to copy the proc directory to save it but it's taking a very long time

Still waiting for the paste to finish.
[Samsung Galaxy Tab Plus] garyd9:
I just need that one file. I'm hoping that it contains the data from your tablet freezing.. if so, it might be very useful.

However, it's almost 4am here, I need sleep, and I have to wake up for work in 2 1/2 hours, so please pardon me if I can't get to it until tomorrow.

take care

gary
[Samsung Galaxy Tab Plus] GTOJim:
Yes please get your sleep I'm still waiting for the paste to finish.

Tab's still pasting the proc dir.

I'm going to bed, unless something unexpected happens I'll upload the file you need in the late am.
[Samsung Galaxy Tab Plus] jasonemorrow:
I did format the card with the tablet. Going to to remove the card and see if they stop again. This is the second today after I rooted, installed most recent kernel. No oc / UV.

Thanks

Jason
[Samsung Galaxy Tab Plus] garyd9:
hrm. I'm assuming that "kmsg" is last_kmsg and "a2" is the dmesg from OS Monitor? Is this the entire last_ksmsg file?

How long, apprx, after it rebooted did it freeze on you? Where you actively using it when it froze up? If so, can you describe what you were doing? Did the screen just freeze (and stay on) or ??

Was the tablet attached to power? A PC? Anything else? (with the exception of the memory card.)

Thank you

Gary
[Samsung Galaxy Tab Plus] jasonemorrow:
Sorry I pulled kmsg instead of last_kmsg.its not rebooted but don't know if this helps. It was an sod pulled dmesg wthin seconds of rebooting.

Thanks

Jason

Also, not attached to anything. No wifi connection, bt off.
[Samsung Galaxy Tab Plus] GTOJim:
Gary here is the file you wanted. I had to kill root explorer, it was still pasting this morning. Guess I should have done that last night and gotten the file to you sooner.

I just gave it a zip extension, it's not a real zip file.

Hope this turns out to be useful.
[Samsung Galaxy Tab Plus] garyd9:
OMG. Thank you. Thank you. Thank you. This proves EXACTLY what I've been trying to tell samsung (yes, I've been in contact with them.)

Your last_kmsg contains an ENDLESS stream of this same message over and over (with only different timestamps):

[ 2963.187494] MsgPend, Invalid Endpoint in look-ahead: 205
[ 2963.187521] Failed to get pending recv messages (19)
[ 2963.187563] Debug Assert Caught, File /home/se.infra/nodeA/workspace/HUDSON_GA_HONEYCOMB_P2-WIFI-BBY_PROD/android/system/wlan/atheros/AR6kSDK.3.1/host/os/linux/../../hif/sdio/linux_sdio/src/hif.c, Line: 1066, Test:status == A_OK || status == A_ECANCELED

Its basically the wifi driver on your tablet is going insane (doing the same thing over and over expecting different results.) The file referenced, "/home/se.infra/nodeA/workspace/HUDSON_GA_HONEYCOMB_P2-WIFI-BBY_PROD/android/system/wlan/atheros/AR6kSDK.3.1/host/os/linux/../../hif/sdio/linux_sdio/src/hif.c" is part of the driver source that samsung won't release.

(You'll see me complaining about that in various threads.)

The bad news is that there isn't a damn thing I can do about this. Without the source for the driver, I'm not even sure if I can work around it. (However, when I have a block of several hours free time, I'll try to figure something out.)
[Samsung Galaxy Tab Plus] GTOJim:
Thanks Gary, at least we now know the cause of the problem.

Hopefully Samsung will be more responsive to your requests.

If not you at least documented the problem so hopefully Samsung will get a fix out sooner than later.
[Samsung Galaxy Tab Plus] jasonemorrow:
Glad I could help. THANK YOU for your hard work.

Thanks

Jason
[Samsung Galaxy Tab Plus] garyd9:
This, however, isn't as useful. It appears that this is from a very short boot up.. the tablet came up, and restarted (normal reboot) 5 minutes later. No errors, no panics... and the last lines indicate a normal reboot:

[ 610.421781] Restarting system.
[ 610.424834] px_reboot

This might be related to the fact that the battery was drained beforehand by the SOD, but I'm not seeing anything to indicate anything unusual in the log.

Please refresh my memory (because I'm VERY overtired right now) - were you one of the ones who could eliminate the SOD by removing the SDCard?

---------- Post added at 08:32 PM ---------- Previous post was at 08:28 PM ----------

Email I sent to the person I'm communicating with at samsung:

(I don't expect any response this week - they are currently celebrating the lunar new year over in South Korea...)

...and now I need to try and rest. 2 hours of sleep last night has caught up with me.

Goodnight,

[Sony Tablet S] ps3taker:
agree with yours plus I would

1) add reverse landscape orientation/4-axes sensor

2) add three more buttons on the left hand side same way we have power,vol up and down on the right so that we could remap them freely to back, home, menu or settings or search, etc. maybe have another place for smaller volume controls somewhere at the bottom

3) add usb charging

4) find a way to have physical playstation controls for gaming

5) make it thinner at the top

6) foldable screen cover turning into a stand

7) xloud - i seem to remember seeing it in the settings but cannot find it again - maybe i'm confusing it with xperia play's settings
[Sony Tablet S] arw01:
Only used the tablet for a couple of hours now.

I hate the charging cord, it's a totally brain dead decision to not use a micro USB port for charging.

The edges need a bit more rounding off, holding the thin edge with the left hand and you can feel it dig in a bit.

Support for larger SDXC cards. Supposed to be able to format certain ones to fat32 and get them to work.
[Sony Tablet S] ps3taker:
I can confirm 64Gb micro sd card using sd card adapter worked and saw other people here had success with 128GB SD card. Hope it helps you

I hope USB charging will be a firmware fix - I remember PSP's originally could not be charged via USB but then there was an update or a workaround.
[Sony Tablet S] rjsmith2007:
Im pretty sure the tablet comes with a screen protector on it. Mine definitely looks like it anyway. I know some other devices come like this as well (the Triumph for instance).

I'd add HDMI out to this device. Make it lighter and less hollow sounding (plastic is okay), improve the back camera (add flash and more adjustable settings), add haptic feedback, improve wifi sleep issues, add PS3 controller connectivity (its already available to rooted users in the market), and finally allow 360 degree rotation by default.

I like the wedge shape, the hidden usb plug, the charger and charging speed, the hidden led notification light, the recessed power and volime buttons, and the two tone black and silver coloring. The color and viewing angles on the screen are amazing.

Id like to note that pushing 2.9 amps through USB would be quite a lot considering normal PC plugs only do 500 mA or 0.5 amps. USB seems like a no brainer until you actually take into consideration the charging time at half an amp. You can push more but the metal starts heating up at that point and you have to add more custom pins for only power (see the Nook Color @ only 1.8amps). Also the thin width of the usb plug does not make it ideal for the structural integrity of the plug on a device that you are going to be moving around.

[Sony Tablet S] vivftp:
Hmm, I just thought about an accessory I think would be wonderful. One of my friends who has the Tablet S also recently got the rooCase Executive Portfolio case which can be found on ebay. It's a lovely case that I'm thinking about getting myself, but my idea is what about the manufacturer making a case like that, but integrating an expandable battery into the case? I mean in something like this you're already adding a fair bit of bulk and some weight to the unit, so why not go the extra mile and add another battery in the case that can double your overall battery life? I know I'd definately buy one if it existed.

access to removable sd card

I would love to be able to access the removeable sd card when attached via the usb to my pc. all I can see is the internal memory.

Also it is a PAIN that songs videos etc are not discovered by the music and video apps.

Otherwise not a bad tablet.
[Android Q&A, Help & Troubleshooting] Cheesus182:
Hey guys,

My phone is troubling me at the moment. Its a rooted HTC HD2 running the Android Nexus.

Now the problem is, that when I install an app from the marketplace it always installs it to my internal memory (approx 128mb) which by now is full.

My SD card has 10GB free space and only has music, videos etc on it but no apps.

I thought that once my internal memory was full it would automatically install the apps to my SD card but it doesn´t do that. It just wont let me download anymore apps and tells me there is insufficent memory.

How do I get it to install the apps to my SD?

Thank you!
