[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] ns4g4me:
Barely installed BBS so I'll wait till I recharge and then I'll see if anything keeps it awake. But here is a screen shot of the os eating up a good chunk of battery. To be honest I hardly use the tab unless my laptop is out so I don't have many apps installed that would keep CPU awake.

Couldn't edit last pic in so here is pic of deep sleep and other states.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] nachordez:
Let's see what BBS says. This android battery app means nothing. System in draining a lot, but kernel cannot do that if there is not an app avoiding tablet to go into deep sleep.

But... You say in your sign you have a 5110, WiFi only, then. But in the stats it says as third consumption cell standby... It you don't have gem connection... Are you sure yo are in a proper ROM, and not in 5100 one? This cell standby is a nonsense, and can be the reason, if its trying to connect to gem without hardware for that...

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] ns4g4me:
I have a 5113 but am running the rc2 for the 5110. Just looked to make sure under about tablet and it says I'm running 10.1.0 rc2 5110. I had noticed the cell standby stuff but thought it was a bug with cm. Here's what BBS says so far about wake locks. But I really dont know what to make of it. Thank u for us response. If worst comes to worst I'll try reinstalling and see if that fixes the problem.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] nachordez:
I don't know what this wake locks are, haven't see them before. Post that in the BBS thread, they will know about that and help you, or try some searching on them.

Anyway, the cell question is strange... I'm also on rc2 for 5110 (5113 is the same really), and don't have that... Perhaps redownload and reflash CM, and, obviously, reflash Dhollmen over it. Never knows...

is it possible to put mpdecision in the kernel/something that will turn off unused cores? i think pegasusq is supposed to do that but when i checked, both cores were being used at the minimum frequency

SD Dead

Possibly dangerous bug!

About 8 hours after i flashed this kernel the tablet didn't detect the sd card at all. Rebooted and reflashed stock CM and i found that my sd card was corrupted(confirmed on pc). I dont know if this some bug or coincidence, if anyone had any similar experience please share.

Thanks a lot

Try reflashing to stock jb, then install the rom you use, then gapps, then this kernel.Let the device boot and let it stay untouched for 5 minutes, so everything optimizes.

ah awesome! i really appreciate it.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Skipjacks:
This could be a coincidence and I have nothing to prove otherwise, but the exact same thing just happened to me.

I flashed this kernel and on reboot the SD Card was corrupted. My PC confirmed the corruption too.

To be fair I also flashed TWRP recovery shortly before flashing the kernel. So it could have been that too. Or it could have even been awierd combination of the two. But I had booted the system and it was working after TWRP. I got the error immediately after the kernel install. Had you done something similar?

Still, two people with the problem doesn't make it a kernel or recovery issue. Two people is still just a coincidence. I'm just putting it out there in case others have had the issue too. If they have then it's not a coincidence anymore.

In any case it doesn't seem like a big deal. I don't think the card is physically damaged as a reformat seems to be curing the problem. It's more like the partition is mildly corrupted or something. I can still read all the data from the tablet. I just get the SD Card corruption error message, and my computer couldn't read the card at all. But a reformat of the card using the CM10.1 ROM's system tools and the card is easily readable in my PC again.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] juanshop:
I've been using the kernel for 3 or so days and I have not experienced this. And I have also flashed twrp before. There must be something else there.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] John_Br:
Neither do I. I've been using this kernel since it came out about a month ago and I use the TWRP recovery even longer. No problem on my P5110.

Grtz,

John
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] juanshop:
Forgot to ask, do you or do you not recommend the highest GPU setting? Or should I stick with whatever the kernel comes preset with?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] tuxafgmur:
I do not believe much in coincidences, but, even if I try, I can't see how kenel can influence in this problem.

The Fat32 partition corruption occurs only (I think so) by a reset of the tablet.

Yet in this case would be the partial loss of data and not likely to break the partition.

I think, if kernel is the problem, it would break the SD card, again and again.

During installation's time, the kernel does not touch the ext-SDcard for nothing.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] tuxafgmur:
The frequency of 1480 Mhz is not supported for all tablets. Even 1420 MHz in some rare case, either.

Generally 1350 is not a bad choice, but my tablet is always 1200 MHz, except when I test.

The kernel boot settings are the best balance between performance and consumption,

but I think there is nothing wrong with higher frequencies.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Skipjacks:
I agree. The SD card is only used to read the zip file of the kernel during installation. There should be no writing to it.

But the kernel could cause an issue when the ROM accesses the card after reboot.

Whatever the error was had to be REALLY subtle though. When it was in the tablet the system settings said the card was unmounted and had errors. But both file explorer apps I have could read the card just fine. I could see all the data on it. Then when I tried to put the card in my computer it didn't work at all.

That is the weirdest file system error nice ever seen. And for the record the ONLY reason I have to connect it to the kernel install was that the error occurred immediately after install. As a general rule I usually remind people that just because an error occurred at the same time as another change, that does not mean the change caused the error. Again I just brought it up so we could see if there is a pattern with the same thing happening to a lot of people. So far there are only 2 of us.

I had that once time ago being on stock. Exactly the same. So I think it's more a problem with device than ROM or kernel...

My sd card got corrupted again yesterday also. I 've flasded the kernel about two weeks ago again and didn't had any problems. Maybe we have something in common that other people dont have... some info about me:

tablet :P5110( the wifi version)

CM :10.1-20130513 nightly

cpu governor : PEGASUSQ

max cpu clock :1350

i/o scheduler : sio (<- maybe the problem is the scheduler, the default cm scheduler is cfq i think)

sd card : kingston 16GB class 10

i dont know if it matters but both time it happened to me after charging ,where the tablet was awake for many hours ( i have enabled daydream with google currents and when it charges the screen doesnt turn off)
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] tuxafgmur:
I do not try to evade responsibility, but we have other components:

- The Rom

- The tablet

- The SD card.

The only time I was directly followed by Spanish forum with an Adata SDcard.

Finaly user confirm that the problem was a damaged card itself as installed on a phone also had the problem.

Myself have two Transcend cards (not damaged) that give Xperia phones problems and work very well on Samsung tablet and phone.

By that I mean: I can not rule out the kernel, but really do not see in what way can influence.

A test at your fingertips is change the scheduler on the other, either row or cfg, if you please to do further testing.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Skipjacks:
Don't sweat it, man. No one is blaming you for anything. We all appreciate you building this.

Narrowing down quirks is all part of the fun of development!:D

The only thing that sticks out on the kernel as being a possibility is how you reworked the ext4 file system driver. That could possibly cause something that looks like an SD card error, depending on exactly what you reworked.

Again, nothing is actually wrong with my SD card. The card does not have an error on it. Nothing is broken. It was just acting like the file system or the partition was messed up. Its like its a fake error.

Its all good, bro! Thanks again for building!

Simply, I worry that something, done for me, might be bothering or damaging the user's work.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] anitgandhi:
I think this is an issue not necessarily with the kernel (but I was hoping that the kernel would fix it) but with cm. Basically I see some lag. For example if I'm in an app and I press the home button then it'll go to home screen but its not smooth, I end up seeing the app as it shrinks into the home screen.

Could it be the transition animation speed?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] tuxafgmur:
That's not a kenel's problem, nor kernel can fix turns giving a rom before executing any action.

I use my own Rom and I've never noticed that effect, but my animation times are reduced or non-existent.

It could be that the system frequency has fallen sharply, and even stopped a processor and the acceleration and frequency scaling noticed. Some launchers are very demanding of resources simply to present a desktop.
