No need to wipe cache / dalvik as guevor explained... but make it a habit of wiping every kernel change

You can find free cpu controllers in the market... you can use one of them...

I am using System tuner pro and find it very useful.... monitoring freq...sd tweak...

freezing apps.. etc.. etc...
[Eee Pad Transformer Android Development] Boss_Cuco:
I do have a cpu controller.... But i can not go past boot screen.

What can i do then?
[Eee Pad Transformer Android Development] devilpera64:
Use CWM for install previous version ;-)
[Eee Pad Transformer Android Development] Nebucatnetzer:
@guevor

That's the formula I was talking about earlier.

It's about undervolting but you can adapt it to the question about "race to idle".
[Eee Pad Transformer Android Development] devilpera64:
I'm on 18b and run basic stress test it seems working well...for now ;-)
[Eee Pad Transformer Android Development] Boss_Cuco:
Previous kernel?
[Eee Pad Transformer Android Development] devilpera64:
Ehm, i think that you have installed last version of this kernel using CWM...so i suggest to install back an oldest but much more stable kernel version...maybe in your case is indicated to downgrade, waiting a better stable version :-)
[Eee Pad Transformer Android Development] Boss_Cuco:
Ive already installed older kernels... And i still get stuck at the eee pad boot screen...

Any ideas??
[Eee Pad Transformer Android Development] baseballfanz:
Try flashing your ROM again. Don't wipe data, that way u don't loose data.

If that don't work then you might need to wipe.
[Eee Pad Transformer Android Development] Boss_Cuco:
Well... I went for it and superwiped everything. Thanks ;)

Its working again.

So... Are there many of you who can use the transformer with 1600/216? Or is it pushing it too much? I guess my chip is one of those that doesnt really like to be squeezed :(
[Eee Pad Transformer Android Development] sidneyk:
I'm on Revolver4 RC1 at 216/1640 all day and night long. Currently, testing guevor's 18b kernel. My tab can go to 1680 and stay pretty stable, 1704 is a bit too much without fiddling with voltages.
[Eee Pad Transformer Android Development] gsantovena:
Confirmed. Only after running games my tablet doesn't wake from sleep and I have to push the power button for 5 seconds to reboot it. I was using test17c. I just installed test18b to give it a try.
[Eee Pad Transformer Android Development] Boss_Cuco:
So, assuming that the problem I had was because of OC what choices do I have to avoid a fullwipe each time it goes wrong?

I mean... I was with 17c, 1600/216 and one day later i couldn't boot my transformer.

What should i do to try... i dont know... maybe 1200?

thanks;)
[Eee Pad Transformer Android Development] Nebucatnetzer:
I don't know how you're overclocking. But when you're trying to find out your working frequency never activate "set at boot". And then go step by step. First 1200 if that's okay go for 1400 and so on.

You might even want to stress test it. Use Stability Test for this. It does a great job and it's very simple.

Then when you finally found your stable frequency you can activate "set at boot" and you're good to go.

Guevor,

Gary said:

We will release 9.2.1.24 into beta testing shortly. This firmware contains new NV code based upon the beta test group who still had issues with .21. I will provide updates once the firmware goes out to the beta group but it did fix returned units that experienced random lockups after .21
[Eee Pad Transformer Android Development] tintn00:
Who is Gary?
[Eee Pad Transformer Android Development] devilpera64:
Guevor, can you open RAM bus or lowering timings for better performaces? :-) any ideas for push out more power for brake other scores? ^_^

[Eee Pad Transformer Android Development] guevor:
I've been focusing on stability and battery, when be more satisfied with it, I will do more performance tests.

Seems to confirm that the origin would be in the nvidia drivers. Anyway this is quite clear that these drivers have problems.

Hopefully it published as soon as possible.

It could be that with some of my tests have created a problem in graphs or simply it is the discussed problem with drivers.

Well, if the formula is correct, means that in case of equal voltage, what you gain in speed you lose in consumption, so you would stay the same. Well, maybe not, because the operation would be better for the user.

Thanks, I'll remember for future approaches.
[Eee Pad Transformer Android Development] devilpera64:
Maybe Asus Italy has understood my post where i was push them to release material for XDA and make a sort of parnership sharing their work :-)
[Eee Pad Transformer Android Development] DammedKiller:
For me test 18b seems so unstable with SOD and battery drain, going back to16b.

Enviado desde mi Transformer TF101 usando Tapatalk
[Eee Pad Transformer Android Development] scottyf79:
17b still going strong for me, approx 130hrs up time with no hint of any problems :D

keep it up Guevor. :)
[Eee Pad Transformer Android Development] Kasimodo:
Same thing here. 18 and 18b => Regular SoD

Go back to v15 that's the most stable for me.
[Eee Pad Transformer Android Development] devilpera64:
Guevor i want leave my feedback regarding 18b:

Pros

- much more responsive than 17b

Cons

- 5Mpx Camera freeze after first long start

- i leaved it in stand-by and i found it in SOD

- a little bit battery drain

-sometimes apps as Opera closes itself

Just for now i returned on 17b :-) tomorrow i'll help Gnufabio for translate some strings in Italian language for revolver RC2 and Revolver Parts :-)

Goodnight to all in the world from Italy!
[Eee Pad Transformer Android Development] gkillerx:
Yep that's what I also thought. I recommend to take a little break and wait and see ;)
[Eee Pad Transformer Android Development] boonkui:
Tried test18b but got SOD. Docked with no SD. Backed to test17c with 180 hours mileage. Thanks.
[Eee Pad Transformer Android Development] joselopez23:
Been having sods on test 18b. Back to 17c. Thanks guevor!
[Eee Pad Transformer Android Development] stewie01:
Me too
[Eee Pad Transformer Android Development] Puzzlegirl:
17c is very stable for me. One SoD from deep sleep early on after flashing but nothing since. It's been healthy for 115 hours now. I haven't tried 18 versions yet.
[Eee Pad Transformer Android Development] schotte:
My TF101 is also very stable on 17c, magatron 1.0.4. I installed 17c 8 days ago and after a couple of days noticed that there was no sound, so did a re-boot and have since had an uptime of over 143 hours with no probs, 16gb microsd in the tablet and 16gb sd in the dock.
[Eee Pad Transformer Android Development] frankyzah:
The BEST at this moment is 17c, 18b sod for me on Megatron1.0.4

Thanks.

Sent from my Transformer TF101
[Eee Pad Transformer Android Development] Danzano:
People that find 17c stable are you sbkv2 or b70+ im on a b60 and 17c was really bad for me testing 18b its been good so far

17 for me was fine but not b or c 18b is fine also

I am just wondering if its the different tf series that make different kernels more stable ?
[Eee Pad Transformer Android Development] DammedKiller:
I just csntell you that I have a sbk2 and 17c was quite unstable. I used to have battery drain and sod, like with 18.

[Eee Pad Transformer Android Development] boonkui:
@Danzano: Yes, 17c is stable on my TF101 with sbkv2 + b70.
[Eee Pad Transformer Android Development] Puzzlegirl:
Mine's B70. 17c is the first kernel I tried that has given me virtually no problems and I have tried them all since test 8 I think. I am able to keep my 32gb class 10 sd card permanently in the dock as well which is a bonus. My TF is 99% docked and only has a few screen lightups now and again if it's left open. I don't really worry about battery life - I charge when needed.
[Eee Pad Transformer Android Development] schotte:
not sure what sbk, but It is a B70.
[Eee Pad Transformer Android Development] woti23:
B60 here

no SOD with dock and sdcard inserted with

17, 17b, 17c and 18b (did not try 18)

ahd 3.2.1, wake min/max 216/1000, sleep 216/456 with ondemand

if the lid is not closed and its in sleep, it now and then wakes up and screen goes on without reason (its not too often so i can live with that)
[Eee Pad Transformer Android Development] CoopZor:
155 hours uptime with megatron rom and kernel 17c.

32gb sd card always in and 99% of the time the keybord is connected.

this one is rockstable for me, thanx guevor !!! ;)
[Eee Pad Transformer Android Development] guevor:
This being quite crazy to track why and when problems arise. It is clear that there are people who do best with some versions than others and vice versa.

I'll try to explain some differences between the versions.

In the 15 did nothing special to prevent problems caused by events generated by the USB (SD card reader is a USB device) while suspending.

In the 16 tried to solve the problem by introducing delays, which sometimes could do that restoring takes more time than normal.

In the 17 instead of pauses, I tried to optimize the on/off the USB hub to avoid such problems.

At 18 I have modified further the process trying to avoid unexpected combinations.

The problem (my fault) is that in addition to those changes (as is so darn difficult to verify the changes, as failures occur randomly and very often time consuming to produce the right combination), I tend to make additional changes to things that I want to try, so sometimes (when I can not devote enough time, like with 18), there is no way to stabilize it.

Anyway, what I mean is that the latest versions are more experimental, and that those seeking stability should stay with the version that works well for them, while evaluate the new versions to find a better combination.

Following this idea, I'll upload a new version so that whoever wants to try it, indicate how it works:

If fail while working.

If fail while suspended.

With screen off but not suspended (USB cable connected or charger)

With or without dock.

With or without microsd

With or without sd.

Thus, instead of waiting for me to try (and probably less time than it produces the error), together we can evaluate it before. (I don't ask that each one try the combinations, try what would normally use and indicate it)

Edit: Uploaded test18c

Undo more changes to try to locate what causes it to hang while charging (it is so random I can not say if remains).

I have simplified the suspension, more like the version 15.

Edit2:

Just after uploading have failed.

Change some thing and upload a new version.
[Eee Pad Transformer Android Development] farsight73:
Your work has been phenomenal... Looking right up to test 18d shown your persistent and support the community would never get even near what Asus can offer..

And this test18d looked promising with most of the reverting changes back to the stable/balance needed in ICS system.

Will test this and report back after some monitoring and observation like 24hrs from now..
[Eee Pad Transformer Android Development] devilpera64:
I can't complete all stress test at higher freq as for 17b...it crash. Before, using 17b i was able to stay always on performances without problems :)

Edit:

I notice that in potrait mode, CPU stay always on max freq and not scale on interactive...it seems use full power to render propely everything.
[Eee Pad Transformer Android Development] keyra74:
is it just me or not, everytime i try these kernels on officiel CM9 nightly i can't get wifi to work
[Eee Pad Transformer Android Development] getbuzzin:
Test 15 is working great for me for a couple of Weeks now. SOD and RR are a thing of the past. I'm very reluctant to switch but will give 18d a try. Again, awesome work as always, very much appreciated.
[Eee Pad Transformer Android Development] thepatman:
Megatron 1.0.4 and 17c is a winning combination for me - cheers bud!
[Eee Pad Transformer Android Development] therock9:
I've been using the official Asus firmwire .21, rooted and change the kernel to test17c version. I am able overclock to 1600mHz which is amazing.

However, I found 2 tiny problems that I am not sure is that related to the kernel.

1. When I plugged into HDMI, I change the HDMI to crop mode but nothing happened.

2. When I opened Youversion Bible app with wifi connection, the apps took long time to load and end up with force close.

Thanks
[Eee Pad Transformer Android Development] devilpera64:
SOD after deep sleep on 18d :-)
[Eee Pad Transformer Android Development] rynosaur:
Me too. Everything was great about late 16x to early 17x as far as sleep of death on dock goes. Why fix what isn't broken? I just flashed back to 17c.
[Eee Pad Transformer Android Development] baseballfanz:
He's just trying to make it better. Great thing is we can always go back to the kernel that work for us.

After all that's why it's still carry the "test" tag.
[Eee Pad Transformer Android Development] yukonking3:
+1 SOD on 18d
[Eee Pad Transformer Android Development] sidneyk:
No SODs or reboots so far...

I've been on Revolver 4.0.2 RC2 and guevor 18d for 8:58 hours with 8:02 hours in deep sleep without issue so far. Current settings are 312 / 1640 interactive and sio governor at default settings and voltages at default.
[Eee Pad Transformer Android Development] woti23:
same here with 18d, SOD after sleeping 12 hours
[Eee Pad Transformer Android Development] Nebucatnetzer:
13.5h up time no issues so far.

No dock, no usb connection, microsd inserted.
[Eee Pad Transformer Android Development] DammedKiller:
I am having 18d and I left my tf sleept at night and it has cosume more thsn 20 percent of battery, don't know why. Back to 17test, the last stable for me.

I am using megatron rom without dock and with micro usb.

What are you, this thread's hall monitor? Shut up.

Part of any development process is feedback from beta testers.

My feedback is: it worked fine before, and now it doesn't. That's why I was sticking with this OC/UV kernel as opposed to the other one on this forum, and I had donated to that guy to no avail.

If anyone else wants to take issue with me having experiences, a TF101, and an opinion, I suggest you go to a linux kernel and type:

echo > /dev/null

[Eee Pad Transformer Android Development] kokopopz:
Same here too. TF with dock and microSD. SOD on 18d.

Back to 17b for now.
[Eee Pad Transformer Android Development] guevor:
Take it easy, don't think you have to say shut up to anyone as I do not think anyone has told you not to comment, if anything, they have repeated what I say recently.

The only way to improve something that works pretty well, is trying something radical, otherwise no progress (or very slowly), and given the nature of this problem, see if it works or not is a lot of time, so that either I am testing every change one week or tested by all and we can test in a week 4 or 5 changes. I've also said before that the last week has been a little crazy for me, so the result was worse.

On the other hand, if the suspension process was perfect, would not touch it, but there are still cases and people who give them problems.

That said, with the test18d (thanks to going back) I think I've isolated the problem that was introduced in 18 (or at least I hope), so I'll upload another version where I am adding some of the changes eliminated , so it should work more like test17, although I have not found the perfect way because there are still potentially unstable cases, but if it's as stable as 17, I will continue from there.

Edit: uploaded test18e

As I said, I hope the problem that caused crashes different than those produced by suspending has been removed, so I am adding the latest suspension code to further improve the process (on test18d I was using an old code).
[Eee Pad Transformer Android Development] j3tt3:
as tester... maybe its better if you mention your rom, cpu settings, etc. etc.

so it will not appear as you are complaining to this FREE kernel...

or say thanks to guevor at least..
[Eee Pad Transformer Android Development] Danzano:
Will try the new kernel now then go to sleep if a wake up to a sod i will let you know and if not then :D

Thanks for all your work and for adding suggestions such as veno/KSM/SIO/experimenting with govs etc etc :)
[Eee Pad Transformer Android Development] Ultimategeppie:
I have been monitoring for a while an like to give my 2 cents also.

* B80

* Revolver 4 rc2

* kernel 18b

* In dock and without dock

* with microSD and SD stuck in

* OC/UC with setcpu to 312/1700

...i only had one freeze.

When i lower the max OC to ~1600 i haven't had any freeze.

To me it seems that a too high freq. gives probs with deepsleep.

Also , i noticed that after a freeze cpy spy says that it can't read the state's file anymore.

I like to try 18e, will do it tonight, when i get home form work.

Only if i noticed something that hasn't been mentioned before I will reply.

Thanx a million Guevor for this fantastic work!

It makes my TF101 alive and kicking!
[Eee Pad Transformer Android Development] boonkui:
Thanks Guevor. Test18d has been stable.

B70, Revolver 4 RC2, 216~1200 MHz, default voltages, MiniSD, no SD. => No RR, no SOD, some screen light-ups, 20 hours.

Moving on to Test18e...

Edit: docked, no USB

Had a SOD on 18e. Used the TF for about 30 min. Put it to sleep for about 1 min. Tried to turn it back on but SOD.

ROM: ARHD 3.2.2

32GB, not docked, microSD inserted.
[Eee Pad Transformer Android Development] timduru:
Tried 18d, had SOD.

It was docked, unplugged with SD card in the dock.

I've attached a kmesg log if it can help.

I was on 17c for the past few days before that and I didn't get any SOD.

Will try 18e, thanks :)
[Eee Pad Transformer Android Development] guevor:
If have failed without the dock must be something wrong in the new version, because it did not happened with previous versions, right?

You care to try a version that I will send in private message, with a small change?

It seems the case I am trying to solve, where the sd card initialization (after the resume) coincides with the beginning of a new suspension.

The 18e should work better, although I am testing a better alternative.
[Eee Pad Transformer Android Development] Thing O Doom:
I don't get any sods normally (so if they popped up there's for sure a problem) so I could do any testing you need done, I have full SD microSD and usb peripherals. Flashing 18e to check now.
[Eee Pad Transformer Android Development] kokopopz:
17b is stable for me docked or not. Can't remember the last time I had SOD with it. :D

Happy to try a new version. But I have just flashed Revolver 4 RC2. Will it matter?
[Eee Pad Transformer Android Development] guevor:
Revolver 4 RC2 should not be a problem, if anything could make the problem arose different, but not create it.
[Eee Pad Transformer Android Development] gkillerx:
Well I can't speak for test 18e but i can for b and D. I am on ARHD and both these versions had an SOD problem. I have no dock, so it was undocked ;)
[Eee Pad Transformer Android Development] yukonking3:
I tried 18e and the frist time the tablet went to sleep it was a SOD. Back to 17c which is stable running Revolver rc2 oc min 216 max 1.4 and ondeman.
[Eee Pad Transformer Android Development] GenghisKhan67:
Same here, going back to 17c for now.
[Eee Pad Transformer Android Development] gsantovena:
I think that is better to test the last kernel from guevor in order to see if it is the one that solves most or all the issues, and help with the development and the community.

I'm trying 18e, and so far so good. I have a TF101 B70 without dock and with an microsd always inserted.

I loaded the 18e version this morning and so far everything is working awesome. Just one question, what's the difference from the regular kernel to the Megatron one? Is it just better to use with the Megatron ROM?
[Eee Pad Transformer Android Development] devilpera64:
No issue with 18e (for now) :-)
[Eee Pad Transformer Android Development] gsantovena:
Mine has two:

1) Not always, but sometimes, when it comes back from sleep, it didn't lock... I mean, turns off the screen and no pattern lock is asked for when I wake it up.

Updated to 9.2.1.21 rooted with CWM and guever's 17b kernel, but now GPS doesn't get satelite lock anymore. Had tried clear GPS cache, reboot and cold boot but nothing help. Anyone having GPS issue on custom kernel or how to fix it??
[Eee Pad Transformer Android Development] j3tt3:
ASUS disabled GPS on the last firmware releases. It works only on wifi as of today.

No idea if they will enable again.

Fingers crossed.
[Eee Pad Transformer Android Development] Nebucatnetzer:
What?! Idiots why would one do that? Maybe they accidently deleted it because it doesn't work

on the Prime.
[Eee Pad Transformer Android Development] farsight73:
What....WTF! Why disable it when it worked perfectly beautiful before..!?

This meant GPS now is relaying its location thru wifi location which also from the telco tower??

Any alternative we could re-enable this?

Geuver, do you by any chance might have an idea to enable back GPS?? May be thru kernel exploit..?

I'm on test 18e now thought 18d giving my GPS issue..
[Eee Pad Transformer Android Development] devilpera64:
Edit: i leaved my B50 on deep sleep all the night and now i found a SOD...however my GPS works very well with Revolver RC2 + Guevor 18e..also only with receiver :-)
