i currently have no problems with the dock charging the tablet but i NOW have my graphics drivers failing on me while playing games which is happening after 21.4 and 22 please be notifyed and try to fix the issue ! ty
[Eee Pad Transformer Android Development] gkillerx:
Geuvor don't know if you already know but:
[Eee Pad Transformer Android Development] marcmarshall:
Ha! Thanks for that. Now I can know what kernel I am running. Especially helpful here because Guevor works so hard for us and is constantly releasing updates.
[Eee Pad Transformer Android Development] Kasimodo:
Sorry for misunderstanding but... is this kernel based on one for TF101G?

Because last for this device is 9.2.2.4 (9.2.1.24 et .25 are for TF101).
[Eee Pad Transformer Android Development] DROITURK182:
the right one for sure.

Yes I downloaded the right kernel for my ROM and wiped data and dalvik cache before flashing. Don't get me wrong v22 is fast as hell but has to many problems with battery drain and the shut down issue.
[Eee Pad Transformer Android Development] mgeniusm:
#608

I was just checking to see if I had 22 installed and saw that 22 is #607 so where the hell have I got #608 from?

Working really smooth with no sods or battery drain, not tried shutting down so don't know if there's a problem there.
[Eee Pad Transformer Android Development] j3tt3:
I suggest that you flash kernel lower than 21.11

(I reverted back to 21.5 Megatron while waiting for the fix)

shutdown issues has been reported to guevor.

for battery drain issues, check what applications (settings> apps) are running.

I have installed Battery Monitor and a task killer to have a -0.1%/hour while on standby. on minimal use (email check, xda premium) my battery last 2-3 days.

btw, what rom you are using?
[Eee Pad Transformer Android Development] inigoml:
With V21, I have experienced SOD with all versions I've tested: V21, V21.4, V21.8, 9, 10 and 11.
[Eee Pad Transformer Android Development] cimbike:
I'm now on 21.4 and so far fo good to me.
[Eee Pad Transformer Android Development] guevor:
As I have no problem with the latest version, I analyzed what might be causing problems with respect to V21.4 and I made ​​three versions for testing.

All versions contain some generic changes over the V22 and also some specific change to the version.

The first (#620) contains a more conservative ram timings , so if the problem was that, with this version should work (only for those who have problems, since it is a little slower)

The second (#621) used the timings of the V22, with some adjustments, and for all types of ram (there are variations between tablets)

In the third (#624) I have removed a change introduced in V22 to see if it was creating problems.

EDIT:

Will try to make a version removing some of the changes between V20 and V21 to see if we can locate the problem.

I used code from 9.2.1.24 (.25 not changed) and from 9.2.2.6 that is the latest for TF101G.

Thanks, no, I don't have read it before.

Thanks. The logs looks normal, the problem seem at cpu hotplug. If not solved with this test versions will continue testing (should be something tricky because not always fails, and never failed for me)

Thank you guys! As I read your answers I realize I could have find the answer myself, sorry for that.

Guevor, and anyone else who has been working on this kernels, thank you very much for all the hard work on this great kernel! :D
[Eee Pad Transformer Android Development] DROITURK182:
Testing your new kernels out

Okay went ahead and downloaded your kernel #621 and everything went smoothly until I tried to shutdown and it locked up on shutdown running newest stock ROM from ASUS. Then went ahead and downloaded the kernel #624 and it booted up fine and right after did a normal shutdown and it shutdown properly. Booted backup and checked, sound, IP tables, both USB slots on dock, SD card slot all work like they should. Going to leave off charger while at work and see if it goes into deep sleep and how it does on battery life, and will right back with findings tonight by midnight. So for short, kernel #621 not fixed, kernel #642 so far so good.
[Eee Pad Transformer Android Development] bkmo:
I can also confer that 621 hangs on shutdown, and 624 seems OK so far.

Edit: next shutdown with 624 hung. Back to 603 or stock for now.
[Eee Pad Transformer Android Development] DROITURK182:
Okay came home from work tonight and the tablet was sleeping like a baby. Meaning that the tablet was in deep sleep for the whole time I was at work from 5pm to 11pm. I went ahead and did other shutdown to make sure, and it shutdown properly again. So the kernel #624 is working great for me. The only thing that bothers me is when i use Google talk with a Bluetooth headset, the voice sounds like I'm a robot also the person I'm talking to sounds like a robot Don't know if this is a kernel issue, but tomorrow i'm going to flash the stock kernel and see if it does the same thing or if it works like it should. but thank you guevor for all your hard work really liking your kernel #624.

Trying now with next build

You all know you can simply type 'uname -a' in a terminal window right?
[Eee Pad Transformer Android Development] cholywell:
Just wanted to point out that the AOKP version of this kernel works great with Team EOS and Gummy ROM as well. Wifi and all.
[Eee Pad Transformer Android Development] FF666:
Did you have problems with 21.11 and Megatron? Because it works so far so good on my transformer. No issues with shutting down, no SOD yet, but only using it for one day.

It seems very very fluent, really like it now...
[Eee Pad Transformer Android Development] alberteske:
I had RR and SOD and boot loop but it was faster than ever.

I am waiting for the new version and meanwhile using 21.5
[Eee Pad Transformer Android Development] lukeborn:
I don't know if the kernel covers the hdmi at all but I've had a problem with the hdmi sending such high volume out that I can't turn the TV down enough to hear it. Also the sound is very muffled making voices not understandable... I have tried this with multiple cables and TVs. I am baffled and really would like to fix this but nothing I have tried affects this.

Thank you in advance!

[Eee Pad Transformer Android Development] Kasush:
I use HDMI out daily and have no issues at all. Samesetup as you without the G.
[Eee Pad Transformer Android Development] FF666:
Ah, too bad. Mine without problems so far, 20 hours now.

I thought everyone was exaggerating with "oohh it is so fast!" But it really is stunningly fast... I'm wondering if it is faster than my friends TF300 in experience :)
[Eee Pad Transformer Android Development] DROITURK182:
I agree just connected the tablet up to my TV using the micro HDMI and everything works like it should. Running stock ROM using kernel #624 at Max 1.2 , Min 314
[Eee Pad Transformer Android Development] mgeniusm:
very strange

I keep reading of sods and other variuos problems, I have tried all the kernals since 21.4 and apart from 22 607 that had bad battery drain I have had no problems what so ever! I have 608 installed at themoment and its working so well I think Ill stay with this one! Thanks for the great work!
[Eee Pad Transformer Android Development] guevor:
Two more test versions.

In the 629 I have made a significant change in basic kernel code, so have to test again that everything is working properly. Hope it works better, but need further tests.

The 631 introduces changes eliminated in the 624.

On the problem of shutdown, it seems elusive, and seems to be not solved completely with the change in 624, so I think that the change I did was facilitating this problem, but the roots should not be in it, so I trying to find the true cause and applied it again.

As I said before, I never turn it off, but who wants to turn it off and not work well, what you can do to avoid the problem is instead of shutdown, reboot to recovery (there are programs for it) and power off from there.
[Eee Pad Transformer Android Development] Mr. Corny:
Thank you, will try 629 right now.
[Eee Pad Transformer Android Development] sidneyk:
To be clear, does 631 only bring back the changes eliminated in 624 or also the 629 changes, too?
[Eee Pad Transformer Android Development] akyboy:
631 hangs on shutt off, megatron... confirm

not biggie for me,... i dont turn it off

checking for rest
[Eee Pad Transformer Android Development] wasdvd:
V22 629 works for me

TF101, 4.0.3 RC3, dock, micro SD in tablet, nothing in dock.

Wifi, Bluetooth, GPS, deep sleep, auto rotate when off the dock all seem to work correctly.The responsiveness seems faster than normal, running my normal .312-1,400 Ghz.

Thanks for your innovative work.
[Eee Pad Transformer Android Development] farsight73:
I think only for 631 which is why there's two kernels up for testing..

But I see the kernel zip size is becoming bigger and bigger.. does all the added files and tweaks really work or play any part in our TF??
[Eee Pad Transformer Android Development] sidneyk:
I tried both v.629 and v.631 and web browsing and navigating the UI seem very smooth and snappy, but something is amiss. Both versions will not play Netflix video at all. The app starts and logs me in fine and brings up the video selection screen, but when I select a video to watch I just get a black screen and eventually the pop-up to choose either to wait or close the problem app. I had to flash an older version to get working Netflix video. I didn't get a log file this time but may try to get it later.

[EDIT] Back to version 22.2-2 build 621 and Netflix video is working good again.
[Eee Pad Transformer Android Development] Mr. Corny:

shutdown properly

diceplayer not working :p
[Eee Pad Transformer Android Development] guevor:
This new version is like 631 (included changes of 629) but with a change specifically to shutdown (please, test and report).

Sorry I can not answer the questions now, because I'm very pressed for time, at least until Friday, if all goes well, on Friday could start a kernel from scratch based on 9.2.2.6, as I commented before. Include only the less radical changes, so should be more near to stock, but with some more performance (although less than the current kernels).

So that the current version would be to achieve maximum performance for those who does not have problems (like me) and the other would make it more stable for those with problems (at least that's the idea).
[Eee Pad Transformer Android Development] antond57:
Start from scratch!

Due to all the current problems, I believe that starting from scratch should be the best option!

Please base this on the stock Asus 9.2.2.6 kernel which is stable for more than 2 days now. The previous 9.2.2.4 was stable for more than 2 weeks on the TG101G using the ARDH 3.3.1_3G and ARHD 3.4.1_3G ROMs while the most of the time was in the deep sleep mode.

Please do not modify to much, only some OC, and I should be very happy and for you a donation when it's working fine on the TF101G.
[Eee Pad Transformer Android Development] akyboy:
Where do you guys download latest stock kernels?

tnx
[Eee Pad Transformer Android Development] sidneyk:
I just tried version 636 and just like versions 629 and 631, Netflix video doesn't work for my TF101, just gives a black screen. I've attached links to logcat and dmesg taken just after trying Netflix on version 636.

Thanks for the log, it have been very helpful.

Obviously the problem was weird, because it not happened to everyone, and thanks to your report, I have been able to detect a major fail.

Is an initialization problem, so you can make it work if do nothing after boot the system and let it suspend. If not, is not well initialized and things fail.

I'll try to fix it in an appropriate manner and will upload another version. If I have no time today, will be on Friday.

Edit:

Fixed version

Later I'll upload the version for AOKP, now I'm late. I changed my ISP to a much cheaper (hard times) and now costs me upload the files about 10 times more.

Edit2:

Added AOKP version.
[Eee Pad Transformer Android Development] sidneyk:
Thanks, I'll give this one a try. I knew I wasn't crazy. Will let you know how it goes. And, you are right, I was checking Netflix first thing after booting and when it didn't work I went immediately to flash another to try. I didn't even think to allow it to suspend and then try.

version 643 seems good

Just tried version 643 and then tried Netflix again. Sometimes on the first attempt, the video will freeze after a few seconds, but the second attempt usually works fine. This was the same with build 621. So, glad to report that this 643 build seems to have fixed my problem. will continue to test other apps and suspend / deep sleep to see how it does. Thanks Guevor.
[Eee Pad Transformer Android Development] inigoml:
TF101, B60 with dock. Revolver 4.03 RC3

build 620 > SOD after 8 hours.

build 621 > Deep sleep for 8 hours, wake up, SOD after 12 hours. Better performance. Dock empty while sleeping during second period.

Now testing build 624. For now, build 508 was the best in terms of stability.

[Eee Pad Transformer Android Development] chatch15117:
It has to be a driver or some kind of tweak like that. How much is the gpu overclocked? The smoothness is night and day. Finally scrolling doesnt seem like it is always trying to catch up to your finger. And pageloads are decent.
[Eee Pad Transformer Android Development] guevor:
The gpu is at 400Mhz which is quite usual when overclocked tegra2 and not usually cause problems.

The point is that the overclocking was done in the test1, everything else has been changes throughout the kernel.

Indeed, there was much time since used the Vellamo benchmark, and has given me a score of 1500 (at 1.2Ghz which is what I use). I think not bad, is the result which gives the transformer prime.

Yes, the log may help locate the problem. Anyway I have not clear whether you mean the hardware video decoding or what functionality and program.

Thank you so much, has been very generous.

I have not found problems with the wifi, but I do not use skype or other voip systems.

Has anyone encountered this problem? Could have been a temporary problem?

Probably still are a few conditions which can cause problems, but fortunately seem to be increasingly remote.

Fortunately, as I have been doing multiple versions with different solutions/alternatives, are earlier versions that may work better for some people.

Anyway, I wonder if you use dock, and if had inserted an sd memory in the dock, or something usb connected.

Because as you say, seems to be more stable, it may be worth trying to fix the 3G before starting with version 9.2.2.6.

A log of a session with 3G with failure could help me to find the problem.

I did not see at the time. Thank you very much.

Can be juiced more GpU's OC over 400mhz?
[Eee Pad Transformer Android Development] guevor:
As promised, I started a new branch of the kernel from scratch, based on 9.2.2.6.

This does not mean that the other was abandoned, much less, because that is what I personally use.

So far I've made ​​the changes I think is most important to improve performance over stock, others to come..

I could not test it (this means it might not even boot) because I use the microsd as part of internal storage, so it should always be running, and the stock kernel disconnects it when suspend and now had no time to take action to avoid possible losses.

This version is particularly suitable for users with TF101G, but if anyone has stability problems with the other, can try this.

If my normal kernel work well, it is pointless to try this, because performance will be lower.

Please if you try it, report if boot correctly.
[Eee Pad Transformer Android Development] antond57:
Maybe as expected, this kernel does not boot on my TF101G BA0.., it stucks on the Asus logo, even after a forced reset.
