I've installed 2.2i first thing this morning.

Around 1PM phone crashed... black screen...

The phone seemed to be ok, just with screen not turning on, because I press the volume buttons and hear sound.

I restarted and did a logcat dump to a file... couldn't identify the error... maybe someone more skilled can take a look?

Only limited governors are loaded by default by the kernel. Rest you can find as modules in /lib/modules. Insert and use whichever you want.

Use voltage control app to change your active governor.

@ droidphile @gokhanmoral and all others

THere is a bug regarding "cell standby" time reporting wrong status, though its not directly related to this kernel,just wanna know is this related to kernel and is it solvable?

Generally the "cell standby" tab shows "time without signal" as 100%, but thats not the case, im having full signal over the whole time.

When i manually goto settings-->about phone--> status ,the signal strength initially stays at 0 asu, but after few seconds it starts reading the signal strength. Once the signal gets read "the 100 % time without signal" decreases gradually, my question here is,

1. Is there any service that needs to be started, to start reading the signal values from boot so that we wont get " time without signal =100 %".

2. Eventhough the signal is full, the cell standby says "no signal" by any chance can this be a factor of battery drain?

Im posting some screenshots regarding this, in the 1st shot you can notice the change of color in phone signal strip, where the color changed only after manually refreshing the signal status.

In 2nd screen after refreshing the signal status manually, the time without signal gradually reduced to 34%, before it was there at 100%

Guessing this would be the case for most of the people here, can we get a solution for this via a kernel update?
[Galaxy S II Original Android Development] kwerdenker:
I don't think that's kernel related. That problem is persistent for me over different kernels, roms and modems. I never noticed any difference in batterylife between the two "cell standby" states, so it's probably just some minor glitch :)

Is it possible that lulzactive cpu governor is not as good appropriate for undervolting as Smartassv2? I got freezes with lulzactive with the same UV-values that I use for smartassv2.

[Galaxy S II Original Android Development] poochewer:

[Galaxy S II Original Android Development] olifee:
I also think that this is the way to go.

An NTFS-formatted external SD gives no real benefits. Its journal makes access slow and wears the SD. Big files can be much better stored in journal-less ext2, which is a nice native filesystem for our device, so mounting can even work cross-kernel (not that I mind, I stay with Siyah :P ) and performance should be better.

Ext4 is also fine, and a bit safer, however, the journal will also increase SD-wear and slow I/O down a bit.

[Galaxy S II Original Android Development] Lownita:
Lulz is very snappy indeed, but I can't find a solution for lagging adw launcher ex. It just lags here and there for sec, being totally smooth again after that.

It seems that the cpu gets clocked down for a sec (or even shorter) abruptly. This is when the scrolling and transitions begin to lag for a short time.

Am using cm7 nightly 114, 200/1200 mhz.

PS: or is the american flag a mistake ?

confusing user info
[Galaxy S II Original Android Development] smitna:
You are right, journalling is deadly over longer time and leads to wear out. That's why I have disabled it for the ext4 partition.

I found this line in /init.rc:

exec apply_system_policy /dev/block/mmcblk0p11 vfat

Maybe this prevents a mount of a NTFS partition, but mmcblk0p11 is the internal one. So mounting a NTFS partition (or every other supported file system) on an external card should be possible without modifications.
[Galaxy S II Original Android Development] tolis626:
On a side note,wouldn't it be nice if we had exFAT support?I mean,we get rid of the size restrictions of fat32 and we don't have to worry about partitioning,wear and that kind of stuff.Unless I'm terribly missing something,we should be moving towards that direction.

Personally,I've formatted an external hard disk where I keep my movies to exFAT and,if we don't take compatibility problems with some devices(e.g. PlayStation3) into account,I'm very happy with it. :)

[Galaxy S II Original Android Development] olifee:
It would indeed be nice, however, if you want native mounting by the kernel, it should be available as filesystem in the linux-kernel.

exFAT is still pretty new (as it is not so wide-spread), and support appears to be only available via Tuxera (if you license it from them) or as work-in-progress free FUSE implementation (which, according to their website, performs quite nice already, they even call it BETA).

You can get the sources with compiling instructions here:

http://code.google.com/p/exfat/wiki/QuckStartGuide

As I have no exFAT-formatted device here (after all, I only use Windows if I have to, and exFAT in a nearly-Linux-only environment is a bit awkward) I did not yet try it myself.

Technically, if you have compiled the binary with an arm-toolchain, it should work the same as ntfs-3g does currently, i.e., for 'real' automounting with unmounting, we would need ROM changes for both, but with scripts, you can mount stuff easily.

@monster, you need to root your phone with cf ( chainfire ) root Kernel, than you can flash siyah Kernel.

You can find CF Kernel here in forum when you use the search. I am not on pc and cant posting a link.

Siyah Kernel is not a Root Kernel but your Root will stay after this.

Hi

First of i would like to thank you for this Kernal, Goes very nice on the Custom ROM am using.

Secondly, am very interested in the NTFS Support

I see that Auto Mounting has been added to this Kernel.

Question i have, is how does this fall on a NTFS SD Card?

I have a 16GB Card and would be nice to copy a File over 4GB to the SD Card for Media Playback on my TV.

Without the hassle of splitting up the file to smaller bits.

Is it supported, or recommended.

(A little disappointed i cannot plug my 500GB External Drive into me phone while Using a MHL Adapter for Playing through me TV :( )

hello. i just want to report a problem i had with my phone, and see if anyone had something similar or it might help the developer.

a few days back my phone went crazy, it started charging itself, went in and out of apps, in and out of driving mode, froze and the battery went crazy from 33 to 14. i was using siyah 2.1.1 with smartassv2 at the time. i talked to gadgetcheck the developer of the rom i use, and he suggested that it might be a kernel and governor issue, and to see this thread. after that i wiped everything and reflashed with speedmod kernel, the yellow triangle removed itself and the battery is charging quicker now.

so if anyone had this issue or knows something please tell me. this is not a complint i just want to solve it and maybe prevent it from happening to others. thanks

You have to set a delay to the init script voltage control creates because something is setting back the max frequency on boot.

[Galaxy S II Original Android Development] frankcilo:
2.2o, for me that I use conservative governor, is the best!

I have also set freq_step to 5, to save other battery life!
[Galaxy S II Original Android Development] gokhanmoral:
just for quick info for others: that means you set the frequency step to 5% of the highest clock.

there are some different approaches. some decrease the sampling interval and also decrease the frequency step percentage and some increase the sampling interval and use higher frequency step percentage.

if 5% performs good for you then keep it, it will save battery.

but I chose to decrease sampling interval to 60000 and set freq_step to 20 for the performance release.

surely it will give you less battery life than the traditional conservative governor, but it will also be more snappy.
