Let me grade some of the posts here:

not bad, but could describe more and could attach /proc/lask_kmsg after a random reboot :p

Quite good almost there... but still missing the all important /proc/last_kmsg file :highfive:

Well below average :(

Below average :(

Well below average :(

To help this kernel BETTER for the community and everyone else, you MUST participate in a constructive manner. One of the MOST IMPORTANT thing you can do is to report detail description of the issue and ATTACH a kernel crash log (/proc/last_kmsg) TOGETHER with your descriptions.... I AM NOT PERFECT or OMNIPOTENT... I can't read your logs across the interwebz... if you want to make this kernel better, active CONSTRUCTIVE participation will make this kernel better and bug free...

:cool:
[T-Mobile, Samsung Galaxy SIII] Crisisx1:
I am running FreeGS3 Sonic R6 with SGS3-ATT-TMO-kernel-tw-011m also with blue mod v3 theme. No reboots or crashes. I also undervolted it a little bit using system tuner, not much tho. battery life seems great. 55% left with 3 hours of screen on time ( so i am on a path to 5-6 hours of screen on time ). WiFi on non stop, listening to music, texting non stop, browsing the internet, editing pics, ran a couple of speed tests and benchmarks. and using many other apps.. btw i have my max freq set at 1.62ghz

this is my first time trying out faux kernel and i like it so far. only complaint is the phone can get a little hot at times but nothing too bad.
[T-Mobile, Samsung Galaxy SIII] ergibson83:
Sorry Faux, I forgot to include the fact that I didnt find a 'last_kmsg' file in the proc folder. There was a 'kmsg' file but it was zero kb. Please let me know what I can do to help. Right now, 11m has been stable, so I'm currently testing it out for reboots. I'll report if I find anything.
[T-Mobile, Samsung Galaxy SIII] clinthess:
I'm running 11u and have not seen a single complication. No reboots or issues with Wi-Fi. Been running smooth on freegs3 r6.
[T-Mobile, Samsung Galaxy SIII] mmorabe:
I've been running Noble 9.1 and just loaded up 11m. Everything was stellar until about 4 hours in today and got random reboots.

Now here's a question that someone might be able to answer: Could a restore from Titanium Backup with App + Data (I use to do App only but accidentally restored data as well) screwed this up since the last backup was from my Galaxy Note N7000? I've tried different kernels already (insecure, Trinity and reventh) and all of these have caused random boots.

Could it be it just be I need to do a clean flash of ROM + Kernel to fix this issue possibly?
[T-Mobile, Samsung Galaxy SIII] jangst123:
Can not find a last-kmsg in /proc or any sub folder.

Found a blank kmsg and something I've never noticed before, a crap load of numbered sub folders almost all created today after flashing 11m

Is this normal?
[T-Mobile, Samsung Galaxy SIII] fiendskillz:
Faux, do you recommend uninstalling CPU Sleeper from Eugene? Is there any reasons as to why it may interfere with the kernel?
[T-Mobile, Samsung Galaxy SIII] faux123:
CPU sleeper is completely pointless and may cause issues.
[T-Mobile, Samsung Galaxy SIII] equlizer:
So this is for the (bell, telus etc) stock firmware correct? Can i flash this and decide to nandroid back to original if i choose?
[T-Mobile, Samsung Galaxy SIII] faux123:
yes. as you stated, make a nandroid just in case :D
[T-Mobile, Samsung Galaxy SIII] stir fry a lot:
Clean flash a rom (factory reset, data, cache, dalvik) and a kernel. Don't restore data from other phones or roms for the most part. Mainly if the flash is from stock to cm or vice versa. Select app data from different roms is usually OK but try to keep it at a minimum if you had any problems.
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Doh! Sorry I didn't get that log for you man...I really shoulda thought of that, but for whatever reason, I just didn't even think of it...

Been back on 10u with no problems, but in attempt to redeem myself I am going to go back on 11u and try to get that for you!
[T-Mobile, Samsung Galaxy SIII] the-Mike_D:
He's right. I see exactly what he sees. There is no "last_kmsg". I'd love to help out as random reboots are the bane of a good phone experience. Would somebody mind explaining how we can get these logs to him in the most straight forward way possible? Even on 10m I've experienced a random reboot once in the past couple of days. But that's a huge improvement over previous builds. Only one negative possible thing is that wifi disconnects 2.4ghz/N sometimes for no apparent reason. I was having trouble even getting onto my 5ghz /N network (dual network router) but wasn't haven that problem with 05 kernel.
[T-Mobile, Samsung Galaxy SIII] jangst123:
I give, went back to 10m after 5 reboots on 11m.

Is anyone getting a last-kmsg on 11m?
[T-Mobile, Samsung Galaxy SIII] faux123:
do you have any cpu profiles or "cpu sleeper" thingy running? my SGS3 has been running for 3 days I've yet seen 1 single failure... what ROM are you using? (I am using 100% pure rooted stock ROM).
[T-Mobile, Samsung Galaxy SIII] mike216:
I'm also without 1 single issue. I've been on my phone a lot also lately? Stock rom with root. If others are having problems you might wanna check out what's going on with your rom
[T-Mobile, Samsung Galaxy SIII] jangst123:
No modifications, just rooted stock.

Can I get an md5 on 11m

I'll re download and try again.
[T-Mobile, Samsung Galaxy SIII] :
I had a lot of reboots as well I'm using wicked rom and 10u is working great for me, 11u was given me constant reboots out of no where btw I don't have set cpu or cpu sleeper only system tuner pro
[T-Mobile, Samsung Galaxy SIII] aznmode:
On FreeGs3 R6 rom running 11m without any issues. But only been running for a day. I also don't use any cpu controller.
[T-Mobile, Samsung Galaxy SIII] jangst123:
I re download and installed.

Still no last_kmsg

So I grabbed a location as soon as I could after a reboot.

Will load log in a minute
[T-Mobile, Samsung Galaxy SIII] faux123:
problem with reports of random reboots without logs is like going to doctor and telling him that you don't feel well and without telling him where, what you ate, how often etc etc.. Good luck finding a miracle cure from that.... Same applies to kernels... I am eager to fix whatever the problem there is for my kernel, but I can't fix what I can't replicate using 100% stock rooted ROM (and I won't test against custom ROMs because who knows what's been changed there, I can only test what I can control).
[T-Mobile, Samsung Galaxy SIII] DocHoliday77:
Ok. I've got a kmsg log for you, I basically ran this in terminal emulator: cat /proc/kmsg > /sdcard/kmsg.txt and then induced a crash.

I have also found that I can force it to crash quite easily by turning off screen, wait a few sec for it to lock and then just keep pressing power over and over. It usually crashes within a few presses. If this method doesn't get you the info you need please let me know and ill try something else.

Btw, I'm running freegs3. If nothing new comes of this ill go back to pure stock rooted like you and try again.

Thanks for everything faux!
[T-Mobile, Samsung Galaxy SIII] jangst123:
Here is a link to the zip of my logcat

https://docs.google.com/open?id=0B_sO8JIq3mZmaGN5U1oxVDRHckU

10m no reboots, 11m rebooting without pattern that I can see.

1 time while on a phone call.

Hopefully the log helps

Any idea why I would not have a last-kmsg in /proc or any sub folder?

Or if all those sub-directories normal?

10U works great for me so it's not a big deal. My Vibrant and SII love your kernels!

I lied!! I do have 1 mod, I installed GoogleNow,, but that has been working fine on 10m
[T-Mobile, Samsung Galaxy SIII] rockenrooster:
Hey faux do you have plans to port your kernel to the sprint version of the S3. I would love to run your kernel on my phone
[T-Mobile, Samsung Galaxy SIII] hiazn:
For last_kmsg try pulling it with adb before your phone fully boots, as soon as it connects to your pc. Some phones delete it at boot.
[T-Mobile, Samsung Galaxy SIII] faux123:
Maybe.. Sprint is a bit different from the GSM phones and since I don't have Sprint version, I am a bit hesitant to do so... I will think about it... NO ETA and NO GUARANTEE

[T-Mobile, Samsung Galaxy SIII] lgsshedden:
Guys, its a noob question but I wanna make sure I do it right. I already have a custom Zaventh kernel for Samsung based ROM, What do I need to do in order to switch to another custom kernel.

Further to what was posted above, it always is a good idea to do a nandroid back up and also one on Titanium of your apps prior to playing with different kernels and roms: not so much the kernels as they tend to be more developed but "custom" roms and themes can cause issues: having a back up allows you to restore your phone, and having your apps backed up in TB, especially using dropbix or the external SD card means you can always re-flash stock firmware in Odin to recover any soft bricks or messy phones from cache clearing not being sufficient.

Quite often people complain to a kernel developer about an issue that is not kernel related at all but a consequence of legacy data left over from previous installs: no offense to anyone in particular but it is just a function of the custom install process. Very rarely are we ever installing a new kernel on a clean phone.
[T-Mobile, Samsung Galaxy SIII] jangst123:
Okay hopefully I caught it in one of the kmsg logs attached.

Phone did it 3 times on phone calls so I thought I could reproduce it and run

adb shell cat /proc/kmsg > kmsg.txt

while doing a phone call, but it will not do it while i have the USB cable and running the command.

So the one log is what I got after it rebooted on a call and I pulled the battery before it booted, then when into recovery.

Another was caught after it rebooted
[T-Mobile, Samsung Galaxy SIII] ewingr:
I just tried both file links in the OP to download, and they appear to be v10 (based on the name of the file that it downloads). Is 11 pulled?
[T-Mobile, Samsung Galaxy SIII] jangst123:
http://faux.androidro.ms
[T-Mobile, Samsung Galaxy SIII] ewingr:
Thanks. I guess the OP just isn't updated yet.

I had a strange thing happen. Installed the Ultimate version of 11. I did one thing out of habit which is not instructed to do in the OP: I ran Fix Permissions after installing the kernel. I've been told to do that on the other kernel I had been testing.

Anyway, what happend was when I booted, it was like I had formatted the SD card. Booted w/o apps, or any of my setup. Hmmm...I wonder if I carelessly selected a wrong item on CWM and did that. Likely...

The good news is I had a Nandroid, and I restored Data, and all is well. We'll see how it goes.

JFYI...my main purpose for custom kernels is to improve battery. However, I have not had much luck with UV settings and keeping my particluar phone stable.

[EDIT]

I had one of those 'random reboots' within 5 min after booting in 11. It happened while working in System Tuner. I had selected an app and clicked on Include, and it froze up, then rebooted.

I went out and found the KMSG file, but it wouldn't let me copy it. Then I read a few posts back that I need the Last-KMSG or something like that, and that I need to use ADB, or something. Don't have time to do that troubleshooting, so I've restored my Nandroid for now.

Also, I don't know if they were there before or not, or if they showed up with 11. I'm commenting on this due to a post a few back about a bunch of numbered directories showing up in PROC. I have a long list of numbered directories. As I said, I don't know if they were there or if they are an issue or not.

I'll watch here and see how it goes for a bit before I try again.
[T-Mobile, Samsung Galaxy SIII] fiendskillz:
I undervolted the kernel and I've been running fine so far with it.. I had it -50 lower but ran into audio skipping.

*this is with v10
[T-Mobile, Samsung Galaxy SIII] ergibson83:
New kernels 12u and 12m are up on Faux's server as of this morning. I'm gonna checkout the 12u kernel and see if he was able to fix the hotboot issue. :good:
[T-Mobile, Samsung Galaxy SIII] play2lose:
On 12m right now. Haven't experienced any reboots yet!

What is everyones favorite governor with this kernel? I'm still using ondemand
[T-Mobile, Samsung Galaxy SIII] faux123:
and you should. Qualcomm phone for STOCK ROM is optimized for OnDemand. Switching to anything else would reduce battery life and performance. :cool:
[T-Mobile, Samsung Galaxy SIII] ergibson83:
So far 12u has been stable for me. Faux is there anything u took from people's posted log files and addressed in this release? BTW u rock dude!
[T-Mobile, Samsung Galaxy SIII] Crisisx1:
Should we never click fix permissions with your kernels?

Just trying out v012m, my first custom kernel on the SGS3. Seems to work well, except adb no longer works.. tried on another computer and with different cables just to be sure.. any suggestions?
[T-Mobile, Samsung Galaxy SIII] jangst123:
So far my phone is liking SGS3-ATT-TMO-kernel-tw-012m.zip a lot better than SGS3-ATT-TMO-kernel-tw-011m.zip

Not a single reboot yet! Thank you!
[T-Mobile, Samsung Galaxy SIII] ewingr:
JFYI...I posted just a few up that 11 caused a reboot on mine within 5 min after install...I installed 12U, did same procedures, and no reboot. So, on I continue with 12U. :cowboy:

BFQ IO Scheduler possibley in the future list?

Just curious. Per the results shown below, I did a test that gave best battery stats using OnDemand, and BFQ on a different kernel I was on, I was doing battery tests with these results:

(Method: Idle testing. That is, Check battery level before go to bed, and then again when getting up. This way it is at least a consistent method to test.)

Other Kernel

OnDemand/Noop - Stock Kernel, Rooted, G1

Overnight/11 hours/15% drop/1.362% per hour

OnDemand/Noop- Rooted, G1

Overnight/12 hours/15%/1.25% drop per hour

SmartAssV2/SIO- Rooted, G1

Overnight/8.5 hours/20%/2.35% drop per hour

OnDemand/Noop - Rooted, G1 - CPU Disabler installed

Overnight/10 ½ hours/12%/1.14% drop per hour

OnDemand/BFQ - Rooted, G1 - CPU Disabler installed: Power Saver off

Overnight/9 hours/6%/.6667% drop per hour

Lazy/BFQ - Rooted, G1 - CPU Disabler installed: Power Saver off

Overnight/9.5 hours/9%/.947% drop per hour

Last night with Faux 12U

Ondamenad/Noop - Rooted, CPU Disabler removed , Power Saver off, UV by 50 on all frequencies

Overnight/7.5 hours/10%/1.33% drop per hour
​
[T-Mobile, Samsung Galaxy SIII] pakraider:
Which is the "other" kernel?
[T-Mobile, Samsung Galaxy SIII] Markdental:
I have come to a conclusion based on these results.

You sleep too much :cool:
[T-Mobile, Samsung Galaxy SIII] Crisisx1:
Lmfao! Right.. Jeez 12 hours
[T-Mobile, Samsung Galaxy SIII] ewingr:
Sammy Kernel.

:laugh::laugh:Well, some of those times include some wake time. But since I am retired, I do get plenty of sleep...usually :cool:

[EDIT]

BTW...I forgot to list on my test with Faux kernel that I did have UV of 50 across all frequencies. I edited it just now.

I plan to test with the deadline IO Scheduler tonight. Will post back results, if anyone is interested. Don't want to clutter this thread if no interest.
[T-Mobile, Samsung Galaxy SIII] mike216:
I thought I had issues, lol..... ;)
[T-Mobile, Samsung Galaxy SIII] jangst123:
Updating my updated.

12 hours on 12m and no reboots

No idea why my phone did not like 11m but it sure likes 12m

I may even grab a fire extinguisher and take 12u for a spin after work :)
[T-Mobile, Samsung Galaxy SIII] ergibson83:
12u has been running fine for me with no reboots. :)

[T-Mobile, Samsung Galaxy SIII] jiovaxrs:
hellow is a diferens when is d2tmo??? or whats d2tmo mean??
[T-Mobile, Samsung Galaxy SIII] ewingr:
Wow. I did the battery test using with OnDemand and Deadline, using 12U. -50 across all freq for UV. It used 34%, over 10 hours, which is 3.4%/hour. Worst battery test so far.

However, Gmail seems to have used a high percentage of the battery. Never seen that before. And TIBU ran during night, I'll do the same test again tonight.

Kernel still working fine. May try a bit more UV.
[T-Mobile, Samsung Galaxy SIII] gordonzhao:
Going back to a previously asked question, what is this other kernel? I'm using Faux's kernel for stock (touchwiz) based roms and I'm not getting anywhere close to these results unless in the 10 hours your phone sits in standby and not used at all and that's how you got 3.4%/hr. Please elaborate with some more details please.

Sent from my Samsung Galaxy SIII
[T-Mobile, Samsung Galaxy SIII] ewingr:
Previously asked question is already answered here.

Some details that should derive an answer was in original post:

The sentence in red should prettymuch indicate that, correct...doing nothing. Idle. That is the only way you can truely get a consistent test method, because iif you introduce any interactive activity, it is impossible to be consistent. Of course I am assuming (maybe incorrectly, who knows) that whatever gives me best idle battery will give me best battery overall.

A bit more information though:

Last night's test I dropped UV another 50 across all frequencies, for a total of 100UV across frequencies

WiFi on all the time

Blue Tooth on All the time

GPS On All the Time

My test last night using the Deadline IO Scheduler was better than previous night (a Titanium backup had run, and for some reason Gmail was active a long time with locks), yielding 1.7%/Hour drop, but still not as good as CFQ, and none of my tests on this kernel has been as good as Sammy using BFQ for IO scheduler.That is why I asked if BFQ may be added, but I never got an answer on that from Faux.

BUT...this kernel is much more stable for my device, and I expect to remain on this kernel.

For those interested in all results of my tests, here is a recap:
[T-Mobile, Samsung Galaxy SIII] waiters:
Does this support init.d?
[T-Mobile, Samsung Galaxy SIII] faux123:
Just a quick note: I know that TMO firmware UVALH2 is now available...

BUT the kernel SOURCE is NOT... I heard that my kernel has WiFi issues and/or random reboots with the newer firmware. I am still waiting for those on the newer firmware to post their LOGS about these things. Meanwhile if you want to play it safe, I would defer the update until the kernel source has been released for it.
[T-Mobile, Samsung Galaxy SIII] the-Mike_D:
Thanks for the tip. I jumped ship for a little while and am running the newer stock kernel UVALH2 kernel until you update. As always, thanks for all your effort.
[T-Mobile, Samsung Galaxy SIII] g2xpolak:
I can't change max frequency. It was stuck at 1.24 with wicked Rom and your older kernel implemented into the Rom. I updated to 12m today and I can't change frequency above 1.13. Can anyone help with this. Using cpu app posted in op

I haven't updated yet but will very soon. Ill be glad to try to get some of the logs you need, but I'm curious, was the kmsg log I got for you when we were having reboot problems helpful. Would that be the kind of log youre looking for this time around as well.

Just want to make sure I did it right so I can correct myself if I didn't!

Thanks for all your work!

Faux 12u and faux12u r_2 what's the difference? Anyone?
[T-Mobile, Samsung Galaxy SIII] Xdenwarrior:
Hey Faux, do u still have a version 009Ultimate cause i had been using that version for over 2 weeks and didnt care for any kernel updates, since it ran really smooth for first time when swiping between pages overloaded with animated widgets and wallpapers, but then i did notice that u tweaked deadline for better performance which is what ive been using and so decided to install 012U yesterday and now i see slight lag again when swiping in touchwiz :( I know its weird, but it seems my phone likes 009 version better.

Ironically, the 009 version did at rarest moments made my phone freeze for like 3 secs when i was constantly tapping things but it was just so Windows Phone Smooth regardless of the dynamic wallpapers and how many apps were open
