It is the second time I passed, I write a response, that costs me to do, publish it (or so I think, don't know what occured) and then I realize that is not.

Anyway, will repeat it.

I don't use a program to overclock, since I use the kernel default 1.2Ghz.

You can use, set cpu, no-frills, os monitor, etc...

To change the voltage I use Pimp my cpu, but I think you can use, System tuner or any other.

When there is a problem of stability from overclocking/voltage, the result is that the processor does not perform as expected, so the result can be unpredictable, since any operation or reading may give a wrong result and ..... anything can happen, usually, or a kernel crash or if it's by too little, a failure of a very demanding program, since failing some of its "more demanding" operations often end up in an attempt to access memory areas not of his property and therefore, the system close the program.

So In the kernel there is no message about the overclocking. What I commented is that if after a game failure, look in the kernel log, you may see a message that might give a clue, like an alloc failure or other error, but if nothing comes out, may be that either be overclocking problem or any problems with the system. The system log (logcat) contains much information of all applications, making it more difficult to find what is important, but are related to the program name.

If no kernel messages out, the first thing I would do is limit the overclocking to see if it still occurs.

Hi Guevor,

Tried using v21 this morning, and I've started seeing the same i2c issues I did with v20 (and I'm pretty sure with stock kernel - the symptoms are the same, the touch screen starts to become unresponsive).

I've attached the kernel.log in case there's anything useful in it, meanwhile I'm going to fall back to the 20.1 test 3/4/5 kernels to see if there's any difference in behaviour.
[Eee Pad Transformer Android Development] gkillerx:
Geuvor in v21 are the nvidia codecs updated or do i need to flash the manually ?
[Eee Pad Transformer Android Development] bkmo:
The codecs are not part of the kernel.
[Eee Pad Transformer Android Development] rtwo:
Wifi is lurking the battery.

I am using cpu master, set it to min 216 max 1200, checking it with cpu spy after several hours, the lowest cpu frequency is 312. The tablet never goes to deep sleep, nor uses 216 Mhz.

I am using latest kernel and latest firmware, back on v.16b i had no problems with battery.
[Eee Pad Transformer Android Development] maxal:
Updated to v21 and my wifi will not connect now, so rolled back to v20.1
[Eee Pad Transformer Android Development] jdcnosse:
so no need to reflash then...

i think it is better to wait before go on 21, many problems i see.

odd problems i must say, i can't imagine guevor make these on release 21.

Waiting for guevor answers...

[Eee Pad Transformer Android Development] gsantovena:
Guevor, first of all thanks for this amazing kernel, I have been using it since test11.

I'm still having the Rooted AnyConnect issue with V21. Below the link with my logcat.

Can you please take a look?

You don't even have to have a VPN configured. The app says that some modules can't load. It works with 17c.

V21:

This is my logcat with kernel 17c:

Thanks in advance.

Quick reply from me; Revolution with 21 and new codecs. Still stable as a rock an fast as hell. (No matter if charging or not, sd or not.) The tablet is just doing it is build for: A stable tablet :-)
[Eee Pad Transformer Android Development] guevor:
The codecs are part of the rom, so if you used my package, your rom was already updated.

I see no reason why not used 216MHz when configured correctly and not see why not go into deep sleep, should see the kernel log to know who has been prevented it.

Cpuspy show me I have been 56 hours, of which 45 in deep sleep and the rest have been using it (the wifi has been on 24 hours, just turn it off at night). All this with one charge of dock+tablet and I have 35% remaining.

What rom are you using? The wifi won't work on a cm9 based without modifying the ramdisk.

On Revolver RC3 the wifi is working me ok.

As I have said to me is working well (can say the best until today), and I have tried many hours before putting it. In fact just look at the uptime of the kernel and tells me that I have 63 hours of which 47 sleeping (strange disparity with cpuspy), I trust much more on the kernel.

I am not using the build I uploaded (I'm using a # 525), because was using it before, and the only thing I changed was adding some debug messages, which I took as test7 and then remove them again (to leave identical to I'm using).

Resuming, I have using a lot of programs, games (I buy the GTAIII to test it, as someone reported that was failing), navigation, youtube, flash videos, music, headphones and the main problem that used to have after such intensive use and long hours (programs closing with failed memory allocation due to fragmentation) has not occurred, the battery has been very good (to be overclocked) and the overall feeling was very good.

Anyway, if anyone has problems, it is necessary to indicate the rom and if possible put a kernel log to see what the problem is, because if not, can be external to the kernel changes and we don't know.

Thanks for putting the two logs, so I can try to locate what fails, because I had tried the program, and the messages it write are not very clear about that part was not working as expected.

Will analyze them, and if I find the problem try to fix it.

EDIT:

I analyzed the logs, and all I find is: "stack corruption detected: aborted" of vpnagentd which does not explain what it was trying to do, or what has failed, only that this process is faulty, because something (I guess something was not expected) has caused malfunction.

The only thing that comes to mind is that changing the compiler and compiler options that I introduced in V20 is causing a problem to the program about something that is assumed to be a certain way and not checked.

Do you remember? (if you tried it), if it worked in version 19.4, because it is the last version before introducing those changes.
[Eee Pad Transformer Android Development] cholywell:
No problems with v21. Left it docked over night with a USB mouse connected and SD card in and no problems. I have the wifi set to disconnect when sleeping and maybe its my imagination but it seems that the wifi connects faster than ever after waking up now!
[Eee Pad Transformer Android Development] AstroTrain:
Hello Guevor,

Here is the latest kernel log for my recent SOD/RR on 20.1. As you can see quite a big file as the tablet ran for some time before shutting down or rebooting. I think it was an RR since the batt drained from 40% to 0. Needed to plug the charger in to reboot.

Unfortunately I need to go back to stock, have to RMA. My Power and volume buttons are so recessed into the tablet that it takes 10 or more tries to boot the thing. I doubt the buttons will last long for me to get back to CMW.

Let me know what you find.

Version 21 seems to cause the video on Netflix to freeze after awhile. Usually I can watch Netflix all night without issue.

[EDIT] Sorry, didn't mean to post here, habit.
[Eee Pad Transformer Android Development] tsachi:
I have the same issue, worked on 17 and 18 but not 20 and up(didn't try 19 since 17c worked great).

Vpn issues relate to the tun module. In the known issues cisco mentions the transformer ics as having some issues. Did you change the source for tun when you changed compile method?

http://www.cisco.com/en/US/docs/sec...connect25/release/notes/rn-ac2.5-android.html

On a side note, there is an ics version that does not require root and should work on the transformer using android native vpn. I haven't tried it, but if guevor can't solve this it may be a workaround
[Eee Pad Transformer Android Development] gsantovena:
I tried the ICS version. It didn't work for me, just the rooted version.

Guevor, thanks for checking it, and it does work well with V19.4.
[Eee Pad Transformer Android Development] galt:
I was ready to give up on ICS on my Transformer, and flashed the V20 kernel and ARHD 3.2.2 out of desperation. 180 hours of uptime later and there have been *ZERO* RRs, SODs, wifi disconnects, launcher failures (loss of icons & widgets) etc....

Excellent work, thank you for your contributions, time, and efforts.

Hi Guevor.

SOD came back after V21.

These last week I've been testing with default kernel in Revolver RC3. It's awesome in terms of performance and battery life. Unfortunately no in terms or performance (I cannot watch Game of Thrones at 720p mkv) and continue with V20. Stable as usual.

However after flashing V21 SOD reappeared, so I'm coming back to V20.

My TF is a B60 with dock. SOD only when dock is plugged and after several hours.
[Eee Pad Transformer Android Development] yukonking3:
+1 for the SOD on v21. Also I notice when downloading a large file like a movie I can not do anything else because the system slows down to a crawl. I am running Revolver rc3 OC at 312 min 1.5 max and ondemand governor. I am back on v20 test 1.
[Eee Pad Transformer Android Development] Thing O Doom:
My second sod ever on 21, reverting to 20.6 for now. What change was implemented with 21?
[Eee Pad Transformer Android Development] guevor:
I compiled two versions to test.

In the first (V21.1) I removed a couple of changes after V20.1test6, to see if they caused instability.

On the second I removed the compiler optimizations to see if the VPN works again.
[Eee Pad Transformer Android Development] Danzano:
Awesome will test asap if a megatron friendly version is up on megatron parts soon :D
[Eee Pad Transformer Android Development] farsight73:
I had been running v21.1 #527 for like 40 hours now and it's working great so far, no problem like RR or SOD.. But however, not tested the VPN of course.

Sent from my awesome rooted Defy: 2.3.6 XDA premium
[Eee Pad Transformer Android Development] guevor:
For me V21 was working perfect, but has some problems has been reported, make some changes to test.

The VPN seems to have problems since V20, so has to be related to compiler options or compiler used, so made a first test with the same compiler but old options.
[Eee Pad Transformer Android Development] ssciberras:
in some prvious version, I had bought Voodoo plus, and installed the last beta, and it was working nicely.

Now running v20, but lost voodoo functionality. Launcghin the application says kernel does not support headphone amplifier controls, and launching the plus control app just crashes.

any thoughts?
[Eee Pad Transformer Android Development] sidneyk:
I just flashed the version 21.1 (build 528) and the VooDoo app seems to work, doesn't give me any message about kernel. The Plus app crashes when you try to launch VooDoo app from it, but it has done this since I installed the beta VooDoo app.
[Eee Pad Transformer Android Development] Pens and DreamS:
Does this kernel work on Wifi Only Asus?
[Eee Pad Transformer Android Development] xbs:
What happens when you press the status bar voodoo icon?
[Eee Pad Transformer Android Development] gkillerx:
Stop asking the same question over and over again! it has been answered for 3 times now!

btw no problem at all here with v21 and voodoo
[Eee Pad Transformer Android Development] Thing O Doom:
21.1 Fixed SoD for me :D Thanks!
[Eee Pad Transformer Android Development] ryan stewart:
I really wish the OEMs would pay attention and bring these geniuses into the fold in some way. His kernel has my up time at 220 hours since I installed it from a tablet that would get the sleep of death or reboot twice a day minimum even after multiple Asus updates.

Thanks!
[Eee Pad Transformer Android Development] devilpera64:
Guevor, i was thought this idea...why you don't create a parallel kernel release for who desire more performances, if today have stable TF101? :-)
[Eee Pad Transformer Android Development] BeavermanA:
What app/method are you using to make the logs for the info you want to see?

I've tried Revolver, Revolution, Megatron and stock with multiple kernels, and I get SOD or RR EVERY time the tablet tries to go into deep sleep. Fresh install, no new apps, microsd card removed, don't dock the tablet the whole time, cold boots, change settings, wipe all data. It does not matter, nothing works.
[Eee Pad Transformer Android Development] septijo:
hi guevor / all people here, im install Revolution 3.4.0 and your V21.1 kernel today.

seems your kernel is good, no RR whatsoever.

i know that your V21.1 kernel is OC to 1.7 ghz, but when i look at CPU spy, it is only 1200 Mhz so far.

a) I look at the "setting", found no setting for CPU frequency. Can i set it manually ? how to make it 1700 ?? or will it be automatically set to 1700 when needed ??? sorry im really new with this OC able kernel thingy

b) I look at the "setting"-"about", there are no "guevor" "V21.1" "528" etc in the kernel. it is "2.6.39.4-g8066a5a-dirty livux@Tragon) )"

how to know which kernel version used inside a TF ?

thanks.
[Eee Pad Transformer Android Development] Salvestro:
For me with aokp milestone 5 and test 21...SOD :(
[Eee Pad Transformer Android Development] 91ludesit:
I've had a couple of SOD's on gummy with V21, but the big deal is the tablet won't deep sleep when it is docked.
[Eee Pad Transformer Android Development] cholywell:
Has any one been able to get wifi to work on the latest Cyanogenmd nightlies? Even the Megatron version doesn't work.
[Eee Pad Transformer Android Development] jdcnosse:
I was on V21 but I was getting screen flickers and so I went back down to V20 and apparently my tablet rarely goes into deep sleep. I left it on overnight just to see, and it spent 12 hours at 216Mhz but only a fraction of that at deep sleep. It's been up for 16 hours now however with no problems other than that.
[Eee Pad Transformer Android Development] Nullinvoid:
it boots default at 1200, you will need to install a cpu OC app like CPU Master to actually overclock it yourself. Look for it in the play store
[Eee Pad Transformer Android Development] tsachi:
No optimization didn't help, VPN still doesn't work with 21
[Eee Pad Transformer Android Development] Nebucatnetzer:
On megatron it's quite obviously why it doesn't work. Kernel need something specific to have a working wifi on it.
[Eee Pad Transformer Android Development] rtwo:
Same here, almost nothing in deep sleep, so i disabled wifi when screen goes off, is a switch in settings, now the tablet goes to deep sleep. Lost 2% battery overnight. Maybe you should check wifi to, i think this started after the firmware upgrade to .24, i have not installed other apps that uses wifi or whatsoever.
[Eee Pad Transformer Android Development] jdcnosse:
Maybe. I thought I had it set to disconnect network services when the tablet's screen was off but I could be wrong. Either way I like the battery it can get with the wifi on. (I keep it on because I don't have my android phone anymore and like to stay connected)
[Eee Pad Transformer Android Development] kokopopz:
v21 works well for me too. 54 hr uptime and 41 hr deep sleep. No RR or SOD. No abnormal battery drain. Not using VPN though.

ROM: Revolver RC3, mSD inserted, docked most of the time but not always, 216-1200Mhz.
[Eee Pad Transformer Android Development] guevor:
To continue with the search of the compile options that cause the failure of the vpn, I have compiled 3 versions.
[Eee Pad Transformer Android Development] septijo:
I'm using Revolution 3.4.0 now. Already tired and gave up on stock ics.

With Revolution 3.4.0 alone, my TF still loves SOD and RR. Mix with v21.1, still give me SOD. So I mix the Revolution 3.4.0 with v17c and... voila .. no SOD.

Go ahead guevor, well done !! Salute !!

I'm a happy TF/ICS/Revolution/guevor user now.
[Eee Pad Transformer Android Development] guevor:
Your tablet is a TF101 or TF101G?

Ok, can you test the other test version I uploaded two post back?

I have a wifi only tablet.

The truth is that it is now occupying me a long time, so make more versions, will be excesive. The result would probably be more problems in both versions.

Anyway, I have no very clear what more be done to improve performance (the last things I had pending was added between V20 and V21).
[Eee Pad Transformer Android Development] darktyroll:
Hi guevor, i dont know if this is relevant but..i use your kernel on my ASUS SLIDER (AOKP rom) from test 16 untill 21 and wanna say NEVER i have any SODs.

I just wanna report on kernel test21 i saw i cannot chose any widgets, i cannot remove any widgets from desktop too. On test20 all work fine for me.

Hope this info will help is something and if not, will remain only an report.

I bow in front of you for your work.
[Eee Pad Transformer Android Development] atomic339:
I get a lot of SOD on AOKP b37.

Tablet is only WiFi so I removed 3 app connected with mobile signal.

kernel V21
[Eee Pad Transformer Android Development] darktyroll:
I tryed build 37 too, but my problems was with widgets how i write up, so i revert on build 36, same bug. But after that i change the test21 to 20 so my problems disspear. You should put test20 with build 37 AOKP and see how it is on you.
[Eee Pad Transformer Android Development] guevor:
For little do not see this message.

Thank you very much.
[Eee Pad Transformer Android Development] guevor:
Another test (not to test VPN).

I made a few changes to the suspend code. If someone wants to test here I put it.

I'll use it the next 24 hours minimum to see how works.

Edit:

Failed some time after suspend while using a sd card.
[Eee Pad Transformer Android Development] BeavermanA:
I'm on a TF101 version B40. Sent you a PM with some logs.
[Eee Pad Transformer Android Development] guevor:
A test version without the support to the dock. If you can test it and report how it works.

Edit:

Changed zip, uploaded the wrong one.
[Eee Pad Transformer Android Development] timduru:
If that can give indications,

I've been using 20.1 test6 for a few days, and no SOD or reboots,

B40 with dock and microsd + SD in the dock.

thanks guevor :)
[Eee Pad Transformer Android Development] akyboy:
i hope no `dock support` is only test,.. not final decision? :)
[Eee Pad Transformer Android Development] guevor:
It is a test, and in any case, would make two versions.
[Eee Pad Transformer Android Development] ssciberras:
This is exactly what happens to me - the voodoo does crash. and launching the beta complains about the kernel.

I remember distinctly that beginning of May I bought licence, and beta was working without crashing.

Maybe voodoo working if app crashes just the same?

and v21 does give me sod when docked
[Eee Pad Transformer Android Development] daranman:
I'm still on 17c with no SODs or RRs on multiple updates on Megatron and Revolver (no dock and OCed to 1400 mhz.). Is there a compelling reason to update other than testing?
[Eee Pad Transformer Android Development] guevor:
Mainly some performance and avoid the problem of memory fragmentation. If you don't have problems with games or gmail that close when you take many hours since last reboot, probably do not need updating.
[Eee Pad Transformer Android Development] guevor:
4 did not work

7 did work

is that?

ricardopvz modified also 6b, have you tested it?

Between 6b and 7 can be the change.
[Eee Pad Transformer Android Development] Nebucatnetzer:
Ah oops sorry forgot that. Yeah 4 didn't work. I'm going to try 6b.
[Eee Pad Transformer Android Development] Nebucatnetzer:
The fix came with 7. 6b doesn't sleep.
[Eee Pad Transformer Android Development] karapoutsoglou:
v.8 is soooo fast but also soooo smooth.

i cannot believe how smooth and responisve everything is.

also i have like 600-700 apps and now the tablet boots in an instant when it used to be like....10 minutes or less.

you are a genius!!!!
[Eee Pad Transformer Android Development] justmara:
wow!

i confirm: test8 @ TFT101G: deep sleep works, no reboots/poweroffs so far. very nice!

... but no wifi o_O. i'll try to look further
[Eee Pad Transformer Android Development] Magikq:
Works pjerfect for me, super speed, great job

[Eee Pad Transformer Android Development] shadrach47:
Sorry if this has already been asked, but has anyone tried this on AOKP? I saw there is a version for CM9, will that play nicely with AOKP? The Dev included build 4 in AOKP but not sure if he had to change anything for it. Thanks

What's that widget\ launcher are you using?
[Eee Pad Transformer Android Development] brando56894:
Running at 1.4 GHz on revolver seems to cause a lot of reboots even though I'm usually perhaps stable at it.
[Eee Pad Transformer Android Development] jwilliamf:
just to answer your question, I'm using AOKP v1.7 (latest) with Kernel-ICS-test8-OC1700-fb.zip at 1504Ghz. Running smooth as butter!!!

..still can not believe how good this kernel is!!!! woof!!!
[Eee Pad Transformer Android Development] scottyf79:
just want to say that with v8 its the first tie ive ever ran stable at 1.6...........never mind 1.7! and even thats running fine! (was only brave enough to run for a few minutes though)

;)
[Eee Pad Transformer Android Development] guevor:
Then it happened when I used the sources from asus version V9.2.2.3. The fix was there.

Already used since test7.

I use normally 1.2Ghz but 1.4Ghz was the second most used and was very stable. Are you changing voltages? On my tablet I lowered it to 1150mv but may be not stable to all, I can change it to 1250 to give more margin.

Have you read my reply. You have on your /system/lib/modules some modules from other kernel, you need to delete it and reinstall my kernel to install the modules. May be not the cause, but it is sure that was not good. Today I will analyze your log in more depth to find if there some other problem, which was very tired last night.

In the next test9 version will delete previous modules to prevent it.
[Eee Pad Transformer Android Development] guevor:
Many many thanks, I'm very happy that my work was useful to other and not only my
[Eee Pad Transformer Android Development] androidfreak007:

Hi

Could not change frequencys via preference panel on CM9 rom with this kernel ...
[Eee Pad Transformer Android Development] linuques:
Great job, guevor. Using test8, deep sleep is working properly and no SOD or RRs.

Thank you!
[Eee Pad Transformer Android Development] Nebucatnetzer:
Try setCPU or another program it works for me.
[Eee Pad Transformer Android Development] j3tt3:
Is there any v 9.2.2.3 kernel which limits the frequency to 1500mhz?

Ive been monitoring freq. (via cpu spy) and there are times that it hits max freq at 1704mhz though i set it up at 1500mhz max freq using pimp my cpu.

The moment 1704 appears on cpu spy... after a few slides on the screen, it will surely crash not unless you lower the freq.

a min 312mhz and max 1504mhz would be sweet! ^___^

Thanks
[Eee Pad Transformer Android Development] cholywell:
Guevor: Any chance you could include the CM9 wifi driver in the kernel?
[Eee Pad Transformer Android Development] tsachi:
I tried all three and the VPN failed, back to 17C and it works. Is there any change in the source between versions? The VPN uses the tun.ko module, any chance the link to that got messed up between versions?
