lots of random reboots on 12/5 cm10 with 12/8 bfs kernel (not OC'ed, zram disabled, ksm enabled, interactive). takes about ~3 successive reboots before system becomes stable again. same with cfs version :(
[Defy Android Development] level_666:
:eek: Sorry! i've read just the last lines of your logs when you turn wifi on/off, i'll buy an OTG cable to test this tomorrow.
[Defy Android Development] funto:
Hi, i have 1 noob question. What is a difference between CFS and BFS kernel and which one should i use for my Defy(green lens) curently running Quark's 18.11. rom. (that were 2 questions actually XD) Thank's in advance.
[Defy Android Development] esok44:
5/12 CMX + 8/12 JellyX killed my phone today, had reboot, then incredible bootloop and then i had to do a datawipe and everything went back to normal...

anyone else had a problem like this?

EDIT: Will not use this Kernel for some time, this was a bad experience, waiting till things change ;)
[Defy Android Development] sergio_sos:
Which one did you used? CFS or BFS?

And if you did a data wipe and all was ok, why did you stopped using this kernel? I am asking because I was about to try it myself.
[Defy Android Development] esok44:
I used BFS. I stopped cause it "softbricked" my phone, want to have a 'rather' stable phone, than one, which reboots often. Liked this Kernel a lot, it was snappy and phone was fast and stuff, but new release of quarx and the following kernel releases, made it too unstable for "everyday me" ;)

Still its worth giving this Kernel a try ;)
[Defy Android Development] renoob:
Excellent question! ;)

What is a difference between CFS and BFS kernel?

Don't forget the OP 3rd paragraph

And... The Expanded Configuration Information Reference Guide to "Kernel Governors, Modules, I/O Schedulers, CPU Tweaks, AIO App Configs" - Awesome
[Defy Android Development] Alka-Seltzer PLUS:
Bfs kernel does not work properly on motoicegun 2.02: governors are there but the phone does not get any signal from the customer neither from WiFi.

Just my 2 cents... :)

Thanks for developing!
[Defy Android Development] Kayant:
Then the build needs to be updated.... I don't know why be the kernel only works on later builds....

Let's Go ^_^
[Defy Android Development] Blechd0se:
Only the kernel from 5.12 wokrs with newer roms because quarx enabled trace support in kernel.

Try a build before 5.12, it should work.
[Defy Android Development] TJKV:
If I build a kernel from your source right now and build CM10 from quarx's source right now, will the two work together? :S
[Defy Android Development] Blechd0se:
Propably yes, but please ask those questions somewhere else :)
[Defy Android Development] YaPeL:
the Rotary Interactivity Favor Scheduler (RIFS) would be a nice add, at least for those who want to experiment a little bit:

[Defy Android Development] mainbord:
I installed cm7 (for defy and defy+, i tested two versions) and installed kernel-cm7-test.zip, defy doesn't boot with this zip.
[Defy Android Development] Blechd0se:
I uploaded a new build, as always appriciate any feedback :)

Propably a good idea and i already tried to implement it, the thing is Fast Open was designed for a newer kernel and there have to be many files rewritten in order for it to work correctly, but at least i started working on it (although i don't think we will get a ~40% boost).

It looks promising, however it hasn't that much benefits compared to bfs while its very hard to implement (lots of 3.x features needs to be backported..)

It's a test zip only for my test purpose, i just saved it there ;)

edit: i don't have that much time in the near future, so don't expect to much from me :)

continuous bootloop after flashing 12/12 cfs kernel. now restoring nandroid..

edit: even nandroid is bootlooping..what the heck? anyone know why these are happening? I'm not sure whether it's the cm10 12.5 build or the jellyx kernel or them interacting with each other..or something else entirely? really don't want to sbf, so i'll try flashing an older jellyX kernel build
[Defy Android Development] niksy+:
12/12 CFS works fine with CM10 (5th December build by Quarx) here!

Did a cache & dalvik cache wipe and permissions fix before rebooting after flash, not sure if it matters though... And it started fine on the first reboot.

I noticed an immediate increase in speed and smoothness of animations :) And that was with interactive+SIO, now off to play with other governors and schedulers!

Thank you, Blechdose!
[Defy Android Development] syllogyking:
sigh guess it's just my device...really need a new phone.
[Defy Android Development] pjgowtham:
Cm7 is the most stablest ever...so I ve been using cm9, 10 since its release...but I find cm7 as still d best..May b I'll volunteer to b a tester for cm7 kernel..

A good kernel for a stabler build would be nice as still cm10 is not ready for a purely stable release and it helps only the testers but not the users who use stable builds like cm7

Thanks in advance...expecting something from u for cm7...u rock!..thank you
[Defy Android Development] super noob bros:
Its not just you, compiled a build with latest commits and it booted. But some of my data was gone (apps still there, but settings lost) and it was hotbooting and rebooting. So flashed the latest quarx build, and now its bootlooping :(
[Defy Android Development] esok44:
Are there problems with reboots or lags or things like that.

I would loooooove, to get back, but after recent events, i am afraid 'cause my phone has to work perfectly ;)

If this build is stable, i will get back to JellyX :D

Blechdose u're great :D
[Defy Android Development] rsk_kelkar:
no problems with cfs. Freezes on bfs
[Defy Android Development] niksy+:
You are actually right, I may have posted a bit prematurely.

When I turn on WiFi the phone reboots after 3 or 4 seconds. Absolutely the same behaviour on BFS and CFS. Gotta get some breakfast now and then I'll see what's in the dmesg.

Okay, dmesg logs attached. Seems to me nothing is saved that happened before a reboot, so don't know if they are usefull...

Whenever it reboots it also wipes something out, not sure about what all, but I know my widgets are gone from the launcher after every reboot.

Just two minutes before, my phone rebooted upon entering messages with my wifi off. That's on BFS (logs, too), going back to CFS now to retest.
[Defy Android Development] Blechd0se:
I can confirm this, however i don't know the reason for this and i thought the same happened sometimes on quarx kernel too.

I uploaded a new testfile (only cfs) and those with random reboots (on 12.12) could try it, if it works i make a bfs version too.
[Defy Android Development] niksy+:
Flashing the new version at the moment! About Quarx's kernel... Well, I've been on the 5th December CM10 for 3 days before yesterday, didn't have a single reboot during that time :rolleyes:

*edit* Flashed... WiFi ON > 6-7 seconds later it rebooted :/ The widgets have remained. But even though I turned WiFi off as soon as it started, it rebooted again a couple of seconds later. This time the Launcher was reset completely, so it started with that "Welcome to your home" (can't remember exactly) screen (I'm not talking about the google account setup).

Reflashing qKernel now :( If you have any suggestions, please share them... Is it working for you completely fine? Together with which ROM? Or if you need more logs (of any kind) just say :confused:

*edit#2* All of the testing was done on a SavagedZen + Noop combo, if it makes any difference. All's well on the qKernel, WiFi active and phone remains on :)
[Defy Android Development] Blechd0se:
I didn't do anything to wifi... and its working fine for me :)

The new kernel.zip was for random reboots, that occur at any time, because i had them. They are now gone and wifi works great for about 5 minutes for me. For governers try to play around a bit and have you changed your vsel settings? Last thing i would recommend is wiping data... or try to let it sleep for some minutes..

Oh and yes i use quarx rom from 5.12 and do you have such problems on a earlier kernel?

Edit:

I use all governors and schedulers, because i have to test them, but mainly brazilianwax + zen or bfq (depends on the things i want to do)
[Defy Android Development] niksy+:
I did change vsels to my usual ones (300/17; 600/32; 800/42; 1100/55) but then did +2 to all of them to see if that could be the instability culprit - no difference.

Will try with a complete wipe tonight after classes (/system /data /cache wipe, install CM10, install JellyX kernel, install gapps) and see if that fixes it! The performance difference really is noticeable, would love to get it working :fingers-crossed:

Oh, and the last previous combination I used was 28/11 CM10 build + 5/12 CFS JellyX, that worked fine! If I get to testing tonight, I'll try running with the 8/12 and 5/12 kernel versions, too.

Mind sharing the governor/scheduler combo that you use? I guess it could be that I've just combined the uncombined... :eek:

Cheers, mate! ;) :good:

I just read this on phoronix, looks like a patch to save memory, dunno how it do it, or, if it can be helpful, but anyway:

[Defy Android Development] super noob bros:
After trying out lots of stuff I realized that it reboots and clears data whenever I change my cpu governor (in my case - ondemand) from interactive. For me, it rebooted twice, and in the third reboot, I lost my app data.
[Defy Android Development] Alka-Seltzer PLUS:
The build is from 12th november 2012 :-o
[Defy Android Development] niksy+:
Okay, so I wiped /system /data /cache, done a completely fresh install with the kernel flashed just after the ROM itself, so the phone hasn't even booted with qKernel once.

It's working stable, completely. Feeling kinda stupid now, because I, too, am pretty sure that the governor was the only culprit, but what the hell... It's working and it's working good, all that matters!

Will try changing i/o schedulers, but not governors, am in no need for wiping for some time :D

Wifi issue with SB3.1

I tried to get the 12.12 cfs kernel to work with SB3.1, no issues with bootup. I went straight to Wifi, it detected my wifi but just couldnot establish a connection. (I had disabled avoid poor connection) I had the same issue with earlier build. I think it is having problem with DHCP. It says connecting but then stops after some time. I changed back to stock SB3.1 kernel and there was no wifi issue.

System info: Didnt fiddle with any kernel settings, so all default, no overclock.

CFS kernel.

Will test it with 13.12 and let you know.

Any one else having trouble connecting to wifi ?

Causes System Freeze on CM10

I was on Quarx's CM10 5th Dec Build. Did cache wipe>dalvik cache wipe>flashed kernel_13.12-cfs>cache wipe>dalvik cache wipe>fix permissions.

The device booted successfully :).Rebooted into bootmenu overclocked it to 1100 mhz which was stable with CM10+qKernal,saved it and rebooted.Then changed the governer to interactive and when i went to change the i/o scheduler the system freezed.Waited for 2 minutes,no response,Removed the battery>rebooted it.Then every thing was working smoothly,received a call>When ended the call,Again system freeze.Rebooted and no matter what governer and i/o scheduler is selected,every time i try to change the governer or i/o scheduler,System Freezes :crying:

[Defy Android Development] sergio_sos:
Ok, I've tried to install all JellyX kernels of 12/12 and 8/12 both CFS and BFS without luck.

I can't make it pass the Google logo on CM10 Quarx 18/11 build. It goes to the black screen and red light only for about 15 seconds and then reboots. I let it go like this for about 15 times and nothing.

Just now I tried with CFS 5/12 and it's now working. I will test it and see how it goes.

Did anyone else tried the newest kernels of 8/12 and 12/12 on 18/11 build?

Maybe the this "08.12: Fixed compatibility with Quarx Rom (05.12)" means that the fix make it unusable on oldest Quarx builds?
[Defy Android Development] Blechd0se:
Yes, that's probably the case since quarx enabled trace support on 05.12.

If you have reboots since the last XX.YY nightly look at the changelog! Maybe i changed something that caused those issues. This helps much more instead of this reports like "..Having reboots on that kernel...".

I can only change what i am aware of. :)

@Da Avenger

Did you tried to wipe data for testing and have you changed the vsel values to fit the overclock?
[Defy Android Development] farsight73:
Quark has made the best possible build kernel and rom in his latest released. The build-in kernel is optimized best to work with his build release. Would stick with it until this kernel really optimized for quark builds rom.

[Defy Android Development] Da Avenger:
Nope,i didn't do the data wipe prior to flashing the kernel.Should i try that way?? :confused: Thought about the clock-vsel instability,so resetted the clock-vsel values the way they were after flashing the same.And still the problem persists :(

we don't need to expect a stable release which is compatible with cm7? Can you please confirm whether or not you are working on it (just to know if it is any hope for this)?

It would be nice because of the weak wifi signal on cm10. I'm also hoping because the proper loop device support (for using a debian chroot).

what did you do exactly?

[Defy Android Development] sanga92:
I have a lot of problems in negan rom before i decided to wipe all and to reinstall it. And from a clean installation i flashed jellyx kernel. ;)
[Defy Android Development] sergio_sos:
So you did a wipe data, installed 18/11 build, and then installed 13/12 JellyX without restarting the phone once? Or you boot up once and then go back to recovery and installed 13/12?

I'm asking because I couldn't make 13/12 boot with 18/11 build. I didn't wipe data. I'm using 5/12 JellyX but I'd like to try 13/12.
[Defy Android Development] zakoo2:
i already was on 18/11 with 28/11 jellyx. i just simply flashed kernel, and wiped cache.

as to your question: its always recommended to reboot recovery after flashing a rom (not after kernel though).

what i mentioned was that a few days ago i had problems with the rom, so i did a full wipe (/system, /data, /cache), and restored /system and /data nandroid. after that it worked good for a while, but now it got a bit slow again with freezes from time to time.

looks like this rom needs a reboot (if not cache or full wipe) once in a while.

sent from my jellybean defy...
[Defy Android Development] sergio_sos:
Oh, so the problem is still there and the phone continue freezing?

Once I have the time I will make a full wipe and try if I can finally install 13/12 JellyX correctly. I hope I don't get the bootloops.

I tried BFS version and experienced several hot reboots, and then bootloops, with Negan and CMX dec 05. Won't try CFS because I reverted to CMX nov 28 (most stable build for me, even CMX dec 05 was sluggish and FC'ing all around, even after a clean install), and it's good as a daily driver, though battery life isn't as good as it was the first time I installed nov 28.

Bad idea it does not work.
[Defy Android Development] Sleepy!:
Running Quarx 05.12 with JellyX 13.12 CFS on top.

I normally OC the phone to 1200/62, but there were so many freezes that I had to revert to the default clock settings...

This marginally reduced the freezes, but I still have to occasionally pull out the battery to restart the phone.

The freezes typically last for 2-5 mins, after which the phone starts working again, with the running process (which froze) FC'ing...

Is there ANY solution to the freezes? Will the BFS kernel make any improvement? :eek::rolleyes:

I'm at the end of my patience now... :(:(:(

PLEASE let me know if any fixes can be done... :(
[Defy Android Development] niksy+:
Be sure to set the governor to interactive, it's the only one that works properly on the latest versions of JellyX. Other than that... Recheck your vsels, don't know what's wrong with it. It was working perfectly fine for me (CFS 13.12 + 5.12 CM10) :confused:
[Defy Android Development] Sleepy!:
It's always been interactive...

Vsels are overvolted now.... UV gave a few more freezes IMO.
[Defy Android Development] zakoo2:
+1, same issue.

i dont think its because of the governor, i tried a lot of them, including interactive, and the freezes still occur then.

the reason could be the cpu leak of download manager, or bad memory management. since i supercharged my phone with more agressive process killing, the freezes dont come that often. it looks as though the phone couldnt free up memory fast enough, and thus the freezes.

i regularly clear the recent apps list, this prevents the freezes usually.

and once in a while i need a reboot, too. maybe theres memory leak?

im running quarxs 18/11 cmx with 13/12 jellyx, and this issue has been present whichever jellyx version i used, so its probably the rom.
