Contant, constant SoD failure to wake up (requires holding down of power button to show any signs of life, first thing I see after holding power for ~5-10 secs is Eee Pad logo) on AOKP. (And constant reboots.)
[Eee Pad Transformer Android Development] farsight73:
After about a day of under .17c with build 9.2.1.17. I had numerous freeze and all I can do is long press power button for reboot. .16 is the most stable for 9.2.1.17 for me. But then I just went on nvflash my TF101 back to clean stock(unrooted) 9.2.1.17 and follow with rooting - CWM and then flash the 9.2.1.21 update zip. Will now try again this .17c and see how it perform under new 9.2.1.21..

At the moment, the new ICS 4.0.3 build 9.2.1.21 looked promising.. Will hang around with this stock kernel until it give me RR and SOD...
[Eee Pad Transformer Android Development] j3tt3:
Megatron and guevor kernels are compatible...

Im now using test17c and its very smooth... No issues so far...

you can flash test16 on Megatron which Ricardo finds it stable...

then you can download test17c, first post on the same thread.... :)

---------- Post added at 09:27 AM ---------- Previous post was at 09:15 AM ----------

Normally guevor set min freq of 312 and max 1200.. interactive

reflash 17c 2 times after wiping cache and dalvik... dont change freqs

disable any cpu controller and battery savers that control freq...

Or may also want to try on another rom...

Sooner you will find the best combination on your TF..

[Eee Pad Transformer Android Development] boonkui:
Just an update on Test17c for my config above. It has been stable for about 100 hours. There are still some rare occasional screen light-ups - each lasted only a few seconds. There were once or twice when WiFi did not reconnect on wake-up; the problem was resolved by toggling WiFi state manually. So, Test17c is the greatest ICS kernel for me so far.
[Eee Pad Transformer Android Development] bsoplinger:
It's not the 2 minutes to flash the kernel I worry over, it's the hours of effort to reflash back to stock .17 then reroot and add in CWM, then find the CWM-flashable version of .21 to get back to stock with root since there isn't a flashable stock kernel available.

You need stock kernel I got stock kernel!

I went through the same thing but I had to do .11 to .17 to finally .21 all rooted rom's so I didn't have to root it once I was done. But you do need to put the stock kernel back on and my advice would to do it before going back to the previous rom's that I mentioned here's a link for the stock kernel and good luck.

[Eee Pad Transformer Android Development] bsoplinger:
Thanks. I've been wanting to try this kernel for awhile but fear of the effort involved in undoing and get back to stock kept me from trying. Now I have the perfect project for tomorrow, full backups both nandroid and Ti, and then a spiffy new custom kernel, woot! :D

[Eee Pad Transformer Android Development] farsight73:
@ DROITURK.. Which stock kernel(.11 / .17 / .21) this belong to?

Here's the quick update if you have .17 rooted with CWM installed and running custom kernel. Just flash this .21 update zip and it will update without touching your custom kernel.

9.2.1.17 to 9.2.1.21

Great work from lizard for this .21 update zip bypassing the verification on custom kernel

Been using this kernel for a couple of days already, and the only bug i've noticed is that the screen turns on randomly (i always use the dock, so i dont know if it happens undocked too).

Btw i use it on 1.5 ghz with interactive governor
[Eee Pad Transformer Android Development] MassStash:
+1 same setup on revolver. but that happened for me as far s i can recall lol not just since i put 17c on here...

~ TF101 on Revolver4RC1

Currently OC'ed to 1.4 with Guevor's
[Eee Pad Transformer Android Development] kalkrishnan:
Thanks for the suggestions. However, the main reason for running guevor kernel for me is the OC to 1.5GHz. 16b works like a charm at that frequency (knock on wood) on my machine with the same ROM. So, definitely something about 17c that causes issues.
[Eee Pad Transformer Android Development] timduru:
I've been using 17c for a few days with dock and SD in the dock,

and it's excellent, no SOD so far as I used to have in the past with an SD in the the dock ! :)

Thanks guevor :)
[Eee Pad Transformer Android Development] devilpera64:
Guevor, news?
[Eee Pad Transformer Android Development] sandman7793:
The same here

My TF has been doing this for awhile now but at least no more RR or SOD and on the plus side the SD card can be in the dock now thank god for XDA. Im also OC to 1.5 on stock rom with bloatware frozen. :D

Just for doubters out there..

Pulled off the charger at 6.15am this morning..sat the throne at 8.30pm to have a news update..

No wifi during the day..and this is what you can get on 17b.. 14 hours and about 7% drain..

Will do the new stock update thanks to lizard over the weekend and see how it settles in..

Battery monitor widget

A few days ago I installed Battery Monitor Widget, the next morning first SOD since 2 weeks.

Uninstalled the app, and now 2 days without SOD. Maybe a tip to other users.

Still on test17, still stable. Nice work. Thanks.
[Eee Pad Transformer Android Development] guevor:
Not sure if I can get at the end a version with the changes I've been doing this week, or will be discarded and a fresh start. The problem is that from the beginning has given me problems, I've been trying to fix it, but added others, and seems that again and again. It is probably because I could not spend too long continued, so have to stop and return many times so I have not been very fine.

I will try to eliminate what I consider most problematic, and I'll see if tonight is stable. If so, tomorrow I will upload a new version, if not, will eliminate all and start again from test17.

Is my tablet compatible with v17c

Hello Guevor,

I have a TF101G (so with 3G inside). It's a B80 model nachorooted using Megatron v1.0.4 ROM.

Until today, I was using your v15 kernel and ALL worked fine. I've tried with the v17 and v17b kernels 3 or 4 days ago but there were too many Sleeps of Death on my tablet so I went back to v15.

But because I was too impatient to wait longer and because I've read on the Ricardopvz 's thread that some users already used your last kernel version (17c), I wanted to try too...

That's for the story. :D

Unfortunately, it was not a success for me.

1. If I wipe cache and wipe dalvik cache, flash kernel and reboot:

- first test: tablet freezes during Optimization of applications

- second test: tablet freezes during "Launch Applications" (just before displaying desktop)

2. After reinstalling v15 succesfully (with wipe cache and dalvik cache), I've flashed v17 without wiping anything. This time, tablet has booted successfully and desktop was displayed. But... I can't use anything except UI. If I launch Opera it freezes before displaying "the square links".

Well... you're writed for comment of this kernel version that "Usb serial changes may affect modems" and I'm not sure to understand what it means.

So can I think that, because my tablet has 3G inside, it may be that my tablet is not compatible with this one?

Anyway, thank you very much for sharing your work.

Best regards.

Sorry I haven't no reply for your question :confused:

Anyway I would like to know more about some apps I can see on your screenshot :D

Can you tell me more (real names or link to Google Play) about:

1. meteo widget

2. Reboot2Recovery

3. "1504 mHz"

4. Mum and Al.... Euuhh no.. .sorry.

5. Turn Off

Regards
[Eee Pad Transformer Android Development] aldur999:
Hello Guevor, I really appreciate your work, but could you please update github repository? I use it to compile some modules I need.
[Eee Pad Transformer Android Development] dgcruzing:
As follows.

1. HD Widgets

2. Reboot2Recovery

3.CPU Master - widget

4. Esfile explorer - file link widget

5. Turn off the lights..have it on all my droid devices, replaces the physical buttons,

thus saves the number of times you have to hit them as its a numbers game..we already have reports of these failing and as on other devices these are one of the weakest links..

Stock Asus kerenels

For those that were asking, I've made a new post in Development:

http://xdaforums.com/showthread.php?t=1636215

It contains some stock Asus kernels, extracted from the US 9.2.1.17 and 9.2.1.21 firmware files and repacked, together with the appropriate included kernel modules. Some were asking for stock kernels to flash in case something went wrong with a custom one.
[Eee Pad Transformer Android Development] tintn00:
Running on Megatron 1.0.4, Megatron parts 1.0.8, and this kernel 17c at default CPU settings (312-1200).

Is there any disadvantage to switching CPU settings to 216-1200? I'd like to conserve battery as much as I can especially on idle, but I'm not sure if there are stability issues.

Thanks!
[Eee Pad Transformer Android Development] sidneyk:
I'm on Revolver4 RC1 and kernel 17c with it set to 216-1640 without issue. Deep sleeps fine with only an occasional SOD. Snappy as hell otherwise.
[Eee Pad Transformer Android Development] tintn00:
What are you using to control the CPU? I'm on Megatron and despite setting minimum at 216 within settings, the monitor never shows the CPU dropping below 312.
[Eee Pad Transformer Android Development] wolvers69:
Thanks for this. I'll be able to flash that update to .21 and then try out 17c. :)
[Eee Pad Transformer Android Development] Nebucatnetzer:
You can go even further.

I'm using a screen off profile with 216- 456 MHz. And when the screen is on it's running at 456- 1400. So it's awesome quick when you are using it and it's using very low frequencies while the screen is of to save battery.

SetCPU does the job very well on Megatron.
[Eee Pad Transformer Android Development] guevor:
Uploaded test18

I have reverted some changes, included test17c ones. I will test the important changes one by one to be sure they work, and release a 18b if they work.

I have test this release only 14 hours, but seems to work well. As I made some "experimental" changes, may be unstable on some untested situation, can cause side effects or if all was ok, be the most stable version to date.

As a curiosity, with this version I have seen the longest period of suspension to date (4.5 hours). Normally, the sistem awake to process something and fastly suspend again, in short periods, normally 10 minutes or less. May be now I'm analyzing it more and I missed it previously.
[Eee Pad Transformer Android Development] guevor:
On the frequencies used (including type of governor) and the battery saver, I give my humble opinion, which may be totally wrong.

If we consider the processor as a unit to which you send tasks to do, we can consider two things that are made as soon as possible at all costs, or carried out with minimum energy consumption.

For the former it is clear that the higher the frequency, before will end, though the further we went, the more consumption. Up here I think we all agree.

For the latter, many people think that putting it at a low frequency, since it consumes the least, that's when we save more, but I think it is a mistake. Just think, to simplify a little, if at 400Mhz the task will be completed in half the time if done at 200 MHz, we can consider that if the processor consumes twice while running at 400Mhz , total spending would be the same. I hope you get the idea.

By this I mean, it would have to know the relative consumption of the processor at each frequency, and the closest I can use is the voltage. The more voltage, the more power/heat.

I, for example, can use 312MHz stably with a voltage similar to 216MHz (750mV), so the performance would be greater than 216MHz, but with a similar consumption, so I think I'm saving battery.

Understand that this is a quick simplification because it would have to know the tables of efficiency at each frequency, and above all, depends on the proper use of the programs because the programs often can "waste" CPU cycles waiting, which performed at lower frequency, we would be saving.

I will try to update it as soon as possible.

Since I don't have a tf101G, I can not test that the changes do not affect 3G, and it seems that one change have affected it. In the test18 I went back to change things that could affect as well.

The only thing I can think of that would help me, would know which exact version problems started, to review what changes I did, remove some and make a test for tf101G to see if the problem solves.

Random reboots or powerdown TF101G (G3 version)

Hi.

I'v still problems with the guevor test 5 using the CM9 build of March 29.

When the tablet goes into the sleep mode, the tablet reboots of stay in the deep sleep mode.

This problem occurs with the stock kernel and with the ICS 0.6 kernel build also.

Please help, it makes me crazy.

The only kernel which is working fine is the stock kernel of the official Asus 8.6.5.21 build.

Btw I'v a TF101G BA0 version.
[Eee Pad Transformer Android Development] karapoutsoglou:
works perfectly with sd increase script.super kernel
[Eee Pad Transformer Android Development] guevor:
Updated first post with test6.

I have increased the top frequency from 1640 to 1700. I may need to increase the voltage to make it stable, I await comments.

I do not know if it works correctly to someone and in general the 1640 wasn't stable. As I do not use the last frequency, can add 1700 without problem, guess who will be the case for most.

I added several i/o schedulers. In general I do not think that bring too much (this would have to prove it), but may make more sense if you use a conventional hard drive via USB.

I've also changed the frequency with which the system boots (unless you change after from init.d like pimp my cpu does. Now the minimum is 312 and maximum 1200.

Never used that, maybe asking in some other thread or testing the stock kernel. If you can find out, please indicate, specially if caused by the kernel.

Have you tried the following version?:

test6-1700

I just flashed and tested test6-1700 version. I tried to set 1700 performance to run quadrant, but the device doesn't even hit 1700 and seems to stick at 1504. I also tried to set 1700 interactive and run quadrant, which gave me my lowest score yet and cpuspy indicates it never hit 1700 but did hit 1600 and 1504. I'm getting a lot of lag and popping in the speakers. I've been able to run 1680 performance and complete quadrant and antutu without problem with Blades meh kernel and maybe a couple others. I think it needs to have more steps (1680 for one) between 1600 and 1700 and perhaps more voltage on the very highest frequencies.
[Eee Pad Transformer Android Development] guevor:
Thanks for the report. As I said, not worked for me at 1640, so it was not clear if it would work. I'll try to raise the voltage and do more tests.

I have applied modifications from V9.2.2.3.

Some changes on suspend, I hope that fixes some stability issues.

I added support to RIL, anyone with a TF101G can check how it works?

Because of the changes could also have new problems, I hope not.

What I've tested so far, everything seems to work well.

I think it's time to get some sleep.
[Eee Pad Transformer Android Development] finalhit:
cool, gonna test it out. minor request: do you mind putting up the md5 on them. makes me feel a lot better before flashing.

anyone know how to avoid the "upgrading" phase during first-boot-after-flash. i typically clear cache and dalvik, so i'm guessing one of these triggers that phase. is it possible to avoid it somehow?
[Eee Pad Transformer Android Development] MarlowXim:

Everything working without problem. Let's see if Asus has just solved reboot problems since with stock kernel I am unable to achieve deep sleep. With performance governor, If I unplug my transformer, it dies when battery gets empty. With interactive one, random reboots.

So I will give a try to this kernel and if it's stable enough I will also test overclocking

[Eee Pad Transformer Android Development] guevor:
I've seen several posts about it and I must say that this kernel is not based on 9.2.1.21. All I did was use some of the changes introduced by ASUS in that version, but do not depend on that version of rom, in fact most were already in version 9.2.2.3 that come from the TF101G.

If at any time I introduce any changes that need something different in the rom, I warn. I usually just use a relatively old rom because lately I have not had time to change it.

Hi guever..

So what or which kernel exactly you're using for this amazing work so far?

And most people here normally recommend to do cache and dalvik wipe prior flashing your kernel.. is this recommended as per your advise?

And why is it has anything to do with kernel and those cache/dalvik cleaning?

Your work had TF101/G users impressed big time and I'm one of them.. Great work!

I'm on 17b right now and will surely test your 18b when it finally out after your throughout test successfully..

Thanks!
[Eee Pad Transformer Android Development] guevor:
Oops. I tried so much the suspension process, which had not proved too much else and think there is a problem. I had not charged battery in several days and put it to load (which prevents the suspension) I had a hang after a while (I guess it's a problem with the lp3 or lp2 states). I have a candidate and I am testing it, if in a few hours does not crash, I'll upload a test18b.

I started from the initial asus ICS source.

Thereafter, all changes that have been introduced are commented in the changelog.

As for clearing the cache/dalvik, I have no reason to indicate a relationship to changes in the kernel, but I do not see any harm in it, and if people are noticing difference, is that there is something I do not see at first glance.

The problem of the power consummation by the cpu relativ to it's frequency leads to quite big discussions.

I can show you a formula, later when I'm back at home, how to calculate the value theoretically.

In the formula the power increases squarely so therefore your theory wouldn't work anymore. However that's the theory and real life situations are different. I came to the conclusion that it's the best to use what you think is the best until a cpu engineer comes and tells us the truth.
