Hacre, just out of curiosity (besides VillainROM) is there another that you recommend for stability? I'm currently using Cognition 1.5 with Ninphetamine 2.1.2 and besides one explicable reboot in a week (even though I'm overclocked at 1.6 but no UV though), the ROM and Kernel are working great together. The phone never overheats (except when playing RipTide HD).

Just wondering if you recommend VillainROM (or any other) over Cognition.
[Galaxy S II Original Android Development] mrabcx:
Had a reboot today on 2.1.1 running a XXKH3 ROM during a Titanium batch backup operation. The crash happened at the very end of the backup procedure, no system OC.

Have attached a logfile.
[Galaxy S II Original Android Development] rodries:
I had a similar problem, but it was TB fault.

I cleanned TB data, and reinstalled TB then all TB problems gone.
[Galaxy S II Original Android Development] darkalchemist:
I'm having problems with bln not working for gosms and emails. I've tried searching the thread for a solution but nothing so far. Suggestions?
[Galaxy S II Original Android Development] desean:
BLN issue is NOT a kernel issue. You are not searching hard enough. :eek:

You should go to Everything BLN instead
[Galaxy S II Original Android Development] lpsi2000:
I don't know if he is going to recommend something but I recommend that use any ROM that works well for you. Find the right combination of ROM and Kernel then have fun. I personal like VillainROM for many reasons which has nothing to do with this kernel:p
[Galaxy S II Original Android Development] weirder:
Just to hook on to this. Not sure if its connected but i had the same problem. Youtube open. Then had a crash (not a full reboot). Also; i cannot view youtube clips. Reinstall of youtube didnt help.

Pretty useless prolly cause i cannot upload a log atm, but wanted to let ya know.

I'll try to test some stuff tonight.

[edit]

Couldnt reproduce from backup so ignore. Nothing to do with this kernel

[/edit]
[Galaxy S II Original Android Development] pulser_g2:
Sounds like youtube app issue unless it reboots whole phone. Perhaps remove all app updates for it from manage applications?
[Galaxy S II Original Android Development] Hacre:
Crash to splash will be ROM or App related, if it's just the app crashing like an FC then definitely ROM or App related. I use Youtube quite a bit.
[Galaxy S II Original Android Development] weirder:
I'm sorry. I wasnt clear enough. Dont know how to call it exactly, but i think its the kernel that crashed. I did not mean an fc.

Wipe youtube data, remove updates, remove youtube app and reinstall didnt help.

[edit]

Couldnt reproduce from backup so ignore. Nothing to do with this kernel

[/edit]
[Galaxy S II Original Android Development] carlos67:
Latest youtube update is very buggy according to market reviews. Try installing the previous version. I'm not updating till they sort the bugs out.

v2.1.6 works perfect. New version is 2.2.1.6
[Galaxy S II Original Android Development] rbalu72:
Just out of curiosity...

Will there be a non BLN variant with new sources in queue or those do not want BLN still better off with 2.0.2??

2.0.2 has been such a magnificent kernel giving excellent battery life...
[Galaxy S II Original Android Development] tolis626:
If you don't use BLN it won't affect you in any way.Just don't install BLN control or anything and it'll be like it's never been there. :)

But BLN is actually usefull.I'd give it a try if I were you.
[Galaxy S II Original Android Development] crypticc:
Apple have that patented if the external power pack is solar powered. Seriously
[Galaxy S II Original Android Development] crypticc:
Hi. Potentially silly question. If I flash the services mod from this thread.

http://xdaforums.com/showthread.php?t=1206726

will it undo anything changed by this kernel that I am using.

thank you
[Galaxy S II Original Android Development] veyka:
No, rom related stuff is er, rom related and nothing todo with the kernel, it supports bln, that's as far as its responsibility goes
[Galaxy S II Original Android Development] weirder:
Reverted to a backup and tried to reproduce this fault. It didnt. So it is not a kernel issue. Not sure how it happend... So... IGNORE
[Galaxy S II Original Android Development] Hacre:
Maybe. I've noticed a few issues with battery life creep in and I think I may have a regression in Samsung's latest sources.

Can anyone remember far back enough to running on a 2.3.4 ROM with an early KG1 kernel, then switching to Ninphetamine? If so do you remember noticing an big improvement in battery life?

Well at least you found it.
[Galaxy S II Original Android Development] jlevy73:
My recollection is that everything up to 2.0.5 had great battery life. Once you updated the source and released 2.1.0, I noticed a drop of. Currently I'm using a KG6 ROM with a KH3 modem. Once I reverted from 2.1.1 to 2.0.5 I've noticed much better battery life.
[Galaxy S II Original Android Development] CamoGeko:
I will be testing this in the coming days, previously I have been running KG6 with Ninphetamine 2.1.0 plus KH3 modem for about a week and constantly getting around 1 day 10 hours roughly out of the battery.

Today I actually reverted back to Ninphetamine 2.0.5 and will be keeping a close eye on the battery life now. Expect some comments coming weekend.
[Galaxy S II Original Android Development] Hacre:
Thanks for this.

It would be useful if the guys testing this can change as little else as possible, like modems. Did you upgrade kernel on your last rom and modem upgrade? If so could it be one of the others, please check, thanks.

In the meantime my honeymoon fast approaches and I'll be returning around September 8th. Unless netarchy beats me to it I'll start looking for power regressions in Samsung's kernel update.

It did also strike me as odd that I had to repair some Makefiles in their uodate2 as well, as they were including files that didn't exist and nor did their directories. To that end, has anyone with the yellow tinge noticed an improvement? I know VPN issues have improved.

Thanks folks.
[Galaxy S II Original Android Development] kalpik:
I can confirm. Used to get around 2-3% overnight idle drain with 2.0.5. Its 7-9% now with 2.1.x. Same ROM, same Modem, same everything.

EDIT: Going back to 2.0.5 right now, will test idle drain again! Expect a report in like ~24 hours :p
[Galaxy S II Original Android Development] goldbergx:
This guy has been testing kernels for battery life for some time now. I don't quite agree with his methodology though and would love to hear what you think about it.

PS - 2.1.0 seems to be doing better than 2.0.5 on this test
[Galaxy S II Original Android Development] designgears:
Easy too, you just creat a /data/system folder with the proper permissions :)

But if they do a data wipe from the kernel then they are screwed... pretty sure that is happening before you could do init scripts.
[Galaxy S II Original Android Development] BAWS:
I´ll switch back to 2.0.5 aswell.
[Galaxy S II Original Android Development] ferreinf:

Hi,

I know nothing of kernels, is this one better than Speedmod?

Performance, battery, etc etc

I only know of speedmod due to his development in kernels for tge original Galaxy S i9000, everyone else is a mystery to me. :)
[Galaxy S II Original Android Development] ragflan:
Thank you. I'll stick to Cognition for now. designgears does a good job.
[Galaxy S II Original Android Development] AndroidGX:
You'd better to test them all, so you can check which kernel is the best for your device, you cannot say 1 kernel eat them all, it's a personal think.
[Galaxy S II Original Android Development] carlos67:
Hmm, I'm feeling tempted to go back to 2.0.5 too. There was a long period of time between 2.0.5 and 2.1.0 and that tells me that 2.0.5 was an excellent kernel (and it was for me - great battery life and rock stable). But, I'm going to sit it out on 2.1.0 on Leo's v2.6 ROM (KH3) till some more reports come in and I've had chance to see what battery is like on 2.1.0 for a couple of days.

Hope you have a great honeymoon Hacre (and Mrs Hacre) ;), you deserve it man.

p.s. hope I'm not being too presumptious by referring to your other half as Mrs ;);););)
[Galaxy S II Original Android Development] chrisjcks:
I was thinking to try this one as its actually compiled from KG5 which is the latest UK leaked FW.

I was just asking for a comparision from someone who may have already tried this and speedmod.
[Galaxy S II Original Android Development] eatonjb:
Going to try 2.0.5 again to see if watchdog stops reporting "*suspend*" and "event/0" using tons of cpu. I'll report back!.

hi did anyone manage to insmod fuse.ko with 2.1.2? I couldn't get the fuse.ko to insmod although it says that this kernel supports it. so far the only kernel I can use to mount ntfs sdcard is cfroot :(
[Galaxy S II Original Android Development] zamana:
I guess that the 2.0.2 is even better because it doesn't have the BLN support.
[Galaxy S II Original Android Development] CamoGeko:
No, its not compulsory to use bln. If you don't want to use it then don't turn it on. Both 2.0.2 and 2.0.5 should have very comparable battery life.

[Galaxy S II Original Android Development] jetshinoda:
so can anyone confirmed that 2.0.5 is still better than 2.1.2 ? i'm still using 2.0.5 and have a good battery life here..
[Galaxy S II Original Android Development] zavenfoizon:
ok guys i have cwm manager and this kernel.zip..

so how to install this? any detail guide ?
[Galaxy S II Original Android Development] jetshinoda:
extract the zImage from the .zip and put it on ur sdcard and then open CWM manager..choose flash kernel option and then choose the zImage u just put in the sdcard...

don't ever change the zImage name btw...
[Galaxy S II Original Android Development] zavenfoizon:
do i have to unzip it ??

i thot i just have to select the .zip file and the device will do the rest..

and i am using leomar 2.6 and gonna flash kernel 2.1.2.. is that kernel buggy or bad bettry life ?
[Galaxy S II Original Android Development] jetshinoda:
u can do that either way :D

not sure about the 2.1.2 though..just got back from the countryside and try to catch up with all this updates...but so far i read...they said 2.0.5 is better...

maybe u can report back when u tried it ;)
[Galaxy S II Original Android Development] zavenfoizon:
okay.. and if i flash this kernel than only ill get access to 1.6 ghz ??
[Galaxy S II Original Android Development] jetshinoda:
yep u can overclocked it to 1.6Ghz...

but the safest is 1.4Ghz...but it's personal preferences actually..
[Galaxy S II Original Android Development] AndroidGX:
Personally I'am experiencing much better battery life on 2.1.2.

I wanted to revert into 2.0.5 to really check the difference but as soon as I flashed it, 1 minute later: random reboot without any UV/OC.. then I flashed back to 2.1.2 and everythings fine.
[Galaxy S II Original Android Development] zavenfoizon:
ok so i can flash without unzip the file na ?/
[Galaxy S II Original Android Development] avetny:
nothing to say....

best kernel for know in SGS2 FORUM.

..........but i still hate u Hacre !
[Galaxy S II Original Android Development] zavenfoizon:
guys what should i do if my device gets continuous boots..
[Galaxy S II Original Android Development] avetny:
wipe wipe wipe !
[Galaxy S II Original Android Development] zavenfoizon:
u meant i should go to clockworkmod recovery mod and clear the cache ? and reboot ?
[Galaxy S II Original Android Development] CamoGeko:
No, you need to wipe everything like data, cache and dalvik cache in recovery.

[Galaxy S II Original Android Development] zavenfoizon:
ow okay... thanks added..
[Galaxy S II Original Android Development] Hacre:
I think when I get back, regardless of the diagnostic outcome of battery life on the old/new sources, I'll provide a BLN and non BLN version of the kernel. People who don't use BLN don't have to put up with the slight battery hit.

That's unless I can fix that slight battery hit, of course.
[Galaxy S II Original Android Development] lbbo2002:
I too have better battery life with 2.1.2. No stability difference with my OC/UV setting (vs 2.0.2 I was on) but overnight is showing ~20% reduced standby drain and the same drain active (web, email, calls, text, YouTube, etc).

YMMV but I only changed the kernel w/Leo's 2.6 ROM and ran it for 36hrs each time with same OC/UV settings.
[Galaxy S II Original Android Development] rbalu72:
wow, that would be wonderful!!

Any way my SGS2 will be in a leather pouch so doesnt matter even if BLN not there for me :p

However I use SGS2 heavily for my office mail purpose so every drop of juice will be quite useful..

hi,

question : does this last 2.1.2 kernel improve the yellow tinting issue ? ...
[Galaxy S II Original Android Development] zavenfoizon:
Guys so I flashed with this kernel and I even got setcpu.. But I am unable to overclock atleast till 1.4.. Not even 1.2..

In setcpu it just extend till 1000..

help me ..
[Galaxy S II Original Android Development] eiraku:
You read my mind.

Was about to ask about the possible battery hit the BLN modules had (if unused), as I don't really care for flashy lights (and yeah I tried em).

Thanks hacre!
[Galaxy S II Original Android Development] CamoGeko:
Did you set it to auto detect frequencies?

[Galaxy S II Original Android Development] chrisjcks:
what is a 'SAFE' voltage for overclocking with setcpu with this phone/kernel?

and when i mean safe, i mean safeeeeeeeeeeeeeee. :)

and what speeds have people achieved without a big drop in battery life?
[Galaxy S II Original Android Development] mynamesteve:
The safest is stock.

Speeds? I achieved warp speed with this kernel also it charges itself, no really. doesn't make coffee though so id stick with stock.
[Galaxy S II Original Android Development] shelter:
Makes sense... but why is there a battery hit if you don't have the app installed to enable it?

Maybe you could add bln as a module that's only being loaded when requested (just guessing here, you might have it as a module already).
[Galaxy S II Original Android Development] jcwww:
No such thing. Every CPU is different.
[Galaxy S II Original Android Development] CamoGeko:
Very true.

Although if you are really clueless like a lot of people seem to be here on XDA nowadays. Try these:

1000Mhz - 1100mV

800Mhz - 1000mV

500Mhz - 950mV

200Mhz - 850mV

---

That's about as stable as it gets with a little UV.
[Galaxy S II Original Android Development] inkyadrian:
Regarding setCPU and the mhz raising to 1000mhz when touching the screen:

I managed to install the Cream Nexus Japanese kernel. When I touch the setCPU, the mhz goes to 500. If I lightly drag my finger across the screen, it shows 800mhz and if I rub it vigorously, it goes to my maximum of 1000mhz. So it seems to be a kernel thing rather than setCPU.

Also, it does not have gps working, loses CWM and I lost root.

Flashing back vis Odin now.
[Galaxy S II Original Android Development] eiraku:
"Cream Nexus Japanese"? God that sounds... ehm... creamy.
[Galaxy S II Original Android Development] alesscam:
this appened because you don't use SetCpu 2.2.4

you can find it's here on XDA ;)

Now flashed clockworkmod and ended up with codeworkx kernel. I did the same test as above and ended up with same readings.
[Galaxy S II Original Android Development] gargon01:
Seemed to be getting a constant 50-60mA drain in standby with the latest 2.1.2 kernel whereas I get 7-11mA with 2.0.5 thus I reverted back. I'm on an odex patched VillainRom 2.4.2 with loads of tweaks and apps but, as I say, I still get the best performance from 2.0.5.

Here's my report, as promised! 2.0.5 does seem a lot more battery friendly than 2.1.2.. Got 2% idle drain overnight once again with 2.0.5, as compared to 7-8% drain with 2.1.2 :)
[Galaxy S II Original Android Development] shelter:
Hard to say for me, I think i had 2% over night with 2.0.5 and with 2.1.2 I have 4%.

BUT... I'm running different widgets since I last measured 2.0.5 so that could be causing it too.

I might have slept longer this time too... :D

Finally had a random reboot yesterday night after 5 hours normal using and this time

Cool, regarding setcpu - the voltages adjust automatically when you increase the speed to either 1.4 or 1.6

(this was after auto detect)

My Quadrant Advanced varies..

1.2 stock - 3700 ish (1300mv)

1.4 - 4300 ish (1350mv)

1.6 - 4700 ish (1450mv)

These voltages are already set when you enable a certain speed. (didnt think it did voltages automatically)

I think it make much more sense to find out what the problems is rather than reintroducing further complications.

"I broke my hand, it hurts a little when i tried to pick a can of beer. Oh well, i'll use it to lift a whole jug since it already hurts"
[Galaxy S II Original Android Development] Hacre:
It isn't modulised, I could look at making it that way as well as an alternative. A battery hit could occur as the BLN code is added into the panel driver and if it has any idle loops where it actively runs a time counter rather than sleeping, that would cause extra battery drain. I just threw whatever the latest BLN support was into the kernel since so many people were asking for it.

Er, first person out of lots to have such an issue, please don't scaremonger about my kernel, it doesn't brick phones. It didn't brick yours either you numpty, it just didn't boot.
[Galaxy S II Original Android Development] s2d4:
Well done, u've managed something unheard of. I am glad u had a jig to save you from the fail.

Kernels do not brick phones, ive flashed shed-loads since the i9000 - the latest version works fine on my 2.3.4 KG5. :)

[Galaxy S II Original Android Development] Pfeffernuss:
A bricked phone is unrecoverable. Your phone was not bricked at all. Just a case of PEBKAC.

Do not misuse the term bricked.
[Galaxy S II Original Android Development] inkyadrian:
I have bricked a Sgs. I flashed, via Odin, 2.3.4 before it was invented. Odin crashed halfway. The phone died. No reboot, recovery, download mode or any screen, even when charging. Windows said it could not find out what I had plugged in via usb. A jig was useless. Total nothing! That's a brick (or a table-mat).

[Galaxy S II Original Android Development] carlos67:
Erm, not strictly true my friend. A bricked phone in the right "expert" hands and with the right tools available can be recovered. Have seen it done on youtube for sgs2.

http://www.youtube.com/watch?v=zN7le4GmxZs (By MobileTech Videos)
[Galaxy S II Original Android Development] Pfeffernuss:
By Wikipedia (I know, doesn't mean sh*t but nonetheless):

"In the strictest sense of the term, bricking must imply that software error has rendered the device completely unrecoverable without some hardware replacement. However, it is common to use the term for a problem which can be rectified but only by a complex and difficult procedure, often requiring additional software."

The common part is used by you, I use the first, and IMHO correct, implementation.

Alas 99% of people here on XDA and other boards use it for everything. Bootloop? Bricked! Acore FC? Bricked! Etc.
[Galaxy S II Original Android Development] desean:
definitely not. for one, i have no issues.

so that the dev wouldn't be faced with posts from users who undervolt too much?
[Galaxy S II Original Android Development] Hacre:
Seemed a completely reasonable setting given that most phones struggle to drop below 825mV for 200MHz. If you think yours can you're welcome to change the clamp and compile your own it's why the sources are made available.

That and before the clamp I had people whining that 750mV crashed their phones...
