Using what software do you get that error, and what sdcard ? Internal or External ?

I need logs, kernel logs and logcats, if you think this is a kernel related bug, otherwise please post in the rom threads....
[LG Optimus 2x] _kankea:
Uhm, Pengus... hlp.

Some pretty serious drain. Happens always just after phone is out of range of connected AP. Normal battery usage with mobile data (3G/HDSPA) is something similar to wifi usage (roughly 1-2 % per /h), but nothing like this. Workaround is to disable and enable wifi, after that battery usage normalizes to 1-2% per h. Tried with your build of CM10 w/ your kernel and everything extra installed (dhcp / wpa), and with newest PA, same thing happens.

Actually, if you have a possibility to try it for yourself, here is how:

- Connect phone to wifi AP.

- Power off AP.

-> Lots of drain.

- from phone -> wifi off & on again -> no drain

Works for me every time.

Logs attached, and some pretty pictures. Disconnected from AP at roughly 19:02.

EDIT:

Attached a screenshot of a normal 3G/mobile battery usage (normal_mobile.jpg)
[LG Optimus 2x] pengus77:
Thanks, i'll look into it. Just for curiosity, does this happen also with stock cm kernel ?
[LG Optimus 2x] dieghen89:
Hi pengus! I've some trouble with the wifi.

I'm on your rom with the last kernel, flashed the dhcp, iwtools and wpa_supplicant (and also just now to avoid any mistake). In kowalsky manager i don't use psp, i think my fonera with dd-wrt doesn't like it.

When i connect to my ap, the most of times i see only a fraction of second the connection estabilished, then the wifi icon disappears and no way to reconnect. Other times i can get the ip but after a couple of minutes, or well a bunch of tenth seconds, i loose the wifi signal. I catched a logcat of this last behavior.

Thanks for your efforts and time!
[LG Optimus 2x] pengus77:
Uhm weird, most probably a problem with your router that doesn't really like the Fast PSP mode. Turn off wifi, then in Kowalski Manager disable Wake PM and re-enable wifi. Check if it behaves the same. If it does it's time to test with another router...
[LG Optimus 2x] _kankea:
Haven't tried because your kernel rocks. With 009 kernel there was no drain but after that... with every newer kernel. I got rid of it for awhile with dhcpcd_556.zip but now, even with fresh install of everything(did not wipe data, though): no dice.

If there's anything I can try, tell me. I can try the default kernel but it'll take some time(=tomorrow) because I'm drunk :silly:

R: [KERNEL][CM10/CM10.1/ICS - OLD/NEW BL][011p3 - 2013/01/28] Kowalski Kernel

Do you know the weird thing? In kowalski manager i don't have wake PM. And looking into /proc/sys (if i remember i should see the wifi folder) i have nothing. The WiFi is on of course.

Edit: forget everything. Flashed again the kernel and seems working. Very weird :/
[LG Optimus 2x] pengus77:
They're in /sys/kernel/wifi_pm since 011 (it's in 2nd post...) and Wake PM should be in the Kowalski Manager that comes with 011p3. If it's not, then you can "echo 1 > /sys/kernel/wifi_pm/wake_pm" and turn wifi back on.

[LG Optimus 2x] natalya:
Hmm.. Sorry for asking, but I remember you once had a long discussion about this and I'm not sure what the conclusion was..

On "About Phone" on ICS ROMs, you don't see Kow@lski under kernel, you only see numbers: 2.6.39.4.. This is normal and just fine, right? I'm on DM 1.4X...

Tonight a stage thing happened, the wifi got stuck on "disabling wifi" (I'm not sure this is the right translation) and drained a lot of battery. The only way to make it work again was to reboot, after that no problem. Shame on me, I forgot to save the logcat. Anyway I'm not sure it's kernel related so don't mind it much. If it happens again I'll post a log...

EDIT: forgot to say, I'm on official cm10.1, 20130128 nightlie, latest Kowalski kernel.
[LG Optimus 2x] ocr66:
I'm sorry pengus, it's external sdcard, I'm not sure why it happened, and I'm not saying is kernel or rom related because it just happened out of nothing, so I'm not blaming anyone, and I don't have a logcat for I didn't noticed it start, just two days ago I unmounted the sdcard to make a backup and started getting two different errors one was I/O error, and the second one was timeout error, tried different computers and with te micro sd adapter and mounted on the phone and got the same erros, so I gues it was my sdcard, so, just to be clear on this, I'm not blaming anyone for I don't know what happened, I was just answering the question made before :)

External sd card. It's happening when I'm trying to archive any folder, or when I'm using TubeMate app (when its downloading the video).

I don't have any logcats, because I'm now outdoor for few days, and I can't learn how to do this and download the app for it.

Btw. I think it's permissions problem. Some days ago i tried to change folder permissions, but 0 effects.

If u can foretell from this it will be good, if not wait when I will got free time :).

I have an sdcard problem too and i don't know what to do with it..i am on pengus rom and latest kernel..when i download files(zips in general) i discover that the zips are empty but the files have the full memory specified before download so it is not a common download problem..also the strangest thing is that when i press properties the md5 has this text: "can't calculate (acces denied)"..i tried cleaning my phone with kaspersky but no luck..tried cache and dalvik wipe..the same outcome:(..

Edit: all this things started when i changed read ahead value..i even created a file 96readahead as described somewhere in this or rom forum(cant remember)..i deleted that file since kowalski manager appeared..but the problem persists

Kernel Update

Oops i did it again :D

This is another maintenance release, nothing really major slipped in, but brings fixes for a couple of nasty bugs (fast charge on the old bl and the shutdown crash). But i really can't just upload bugfixes releases, can't it ? It's not in my nature... so, well, i added Boost Pulse to give you a little bit more project butter experience ;)

011p4 - 2013/02/03 - Bugfixes and some goodies

* Backported OnDemand governor from kernel 3.2

* Added Boost Pulse support in the kernel for Interactive and OnDemand governors

* Added tegra.power.so blob to the installer

* Optimized CFQ and BFQ schedulers

* Fixed shutdown crash

* Fixed USB fast charge on the old bootloader

* Updated Kowalski Manager to the latest version​

All new releases from now on will be pushed to my folder on XDA Fileserver here in the Releases subfolder. From time to time you'll see kernels popping up in the Testing_DONT_DOWNLOAD folder... well... don't download them :D

Update: I'll keep pushing 011pX updates until The Next Big Thing™ is stable as a rock, so mostly small updates if the kernel is reliable... but something big is coming your way ;)

Get them from the second post. Although if you didnt reflesh the Rom those are a once only flash.

So if you are only flashing a new kernel there is no need to reflash them.

So regulating tx power does not work at all in the latest release or it is just not displayed right in iwconfig.

Also pengus I saw your post about testing the processor OC and you said it is unstable and wont make it into public release....but what about the GPU OCing?

Also to report a problem: With tonyp build 4 i have a problem when the display brightness custom value but not automatic. When i press the hardware button to unlock the screen dims for a half a second and then goes to the normal brightness setting fast. I would provide a logcat but Lumberjack freezes at 50% of exporting logs. I am on OLD BL, kowalski 11p4 kernel,tonyp pa build 4.

That stupid idiotic pengus77 implemented OC in a smart way, it will throttle once it hits critical temperatures.

Yes, it ensures my battery won't overheat and will protect the phone from damage.

Yes it probably is the best and most stable OC implementation the Optimus 2x ever had.

Yes, this is OCing how it's supposed to be.

[LG Optimus 2x] robbie2k:
Hi guys, I just installed the CM10 By Pengus (last build) + Kowalski Kernel 011p4, everything went fine with the AIO tool (great tool).

I also flashed the wpa_supplicant and the p990-sdswitch-newbl.zip patches.

I see some battery drain, it gone from 100% to 73% in 2 hours (only playing with settings), I don't know if I need to apply some patch more to reduce the battery drain.

But what's a bit strange is the app managing by the system: The system is correctly recognizing the ExternalSD as InternalSD (in fact the internal is empty, and the external contain the android typical folders), so I tried to install some apps (games) and I see that they are installed in the internal storage (not the internal SD but the internal storage, the one with about 1,45 Gb free when is empty), that is normal, but I can't move some of them on the MicroSD, because in the app info the button to make this is disabled.

The usb mass storage don't work.

Another doubt that I have is about the ramhack, is not possible with this kernel? I tried to go in the terminal, writing su (all ok), but it don't recognize the command RH.

What could be wrong?

BTW for what I can see until now it's an amazing kernel (and ROM), many compliments for the job guys.

I don't know if this is supposed to be a feature or a bug or ROM problem or whatever but I noticed wi-fi scanning doesn't work properly.

I was out in the street scanning free APs when I moved to other places it kept showing always the same networks even forcing a scan didn't work. Wifi was still on when I came home when the phone would automatically connect to my home network but i didn't, it was still showing the same networks, they only way to make it connect was to turn wifi off and then on.

Is this a forced battery-saving feature?
[LG Optimus 2x] robbie2k:
Thank you Carlo (all italians here? :) )

I was reading that RH was present but was thinking that was needing to activate it with an option.

Any suggestion about the battery drain (a bit excessive imho, I repeat, 27% of battery is gone aftter 2 hours of use, only playing with settings, and without zero app installed, normal?) and the usb mass storage (this kernel support it or not?)

Maybe I haven't installed some necessary patches, until now only IntSD-MountFix, wpa_supplicant_8_updater, p990-sdswitch-newbl, dhcpcd_556_jb and NitzDisabler. nothing about the wi-fi energy saving, I need something more to preserve the battery?
[LG Optimus 2x] pengus77:
Hey there,

if you're on CM10 (or CM10 based roms), you need to flash the wpa supplicant and dhcp packs in 2nd post to have wifi working correctly ;)

Anyway, i studied your earlier log more and went researching about your crash and i found out it's a linux kernel bug present in 2.6 and fixed in 3.X... so i backported the fixes and they'll make their way in the next release. No need to bring your phone into service :D
[LG Optimus 2x] pengus77:
27% with 2 hours of screen on time is a bloody record for the P990... consider, and i say this for the hundredth time, that having more than 4 hours screen on time on a modern phone is something really rare. I invite you to go look in the gnex or n4 kernel threads and admire the users happiness when they post a 4 hours screen on time screenshot :D

Usb mass storage works perfectly here... you need to disable android debugging to have it work though. It's not a kernel problem.

Profiling

Hi pengus77 I just want to ask you if you can publicly release the vmlinux file of your great kernel. I know it is useless for BFU but I try to profile system with some glitches (some applications are opening way tooooo slow - for example opening Configuration takes about 20secs) so I profile it and sees the 70% is in kernel. I don't want to say the issue is in kernel, but want to see if I have made some bad customization which prevents this slowness.

Anyway thank you - without Kowalski kernel the CM10.1 is useless...
[LG Optimus 2x] pengus77:
Yeah, you can compile the source for this kernel from github and test on the output if you want... but i don't seem to have any slowdown or lag here, nor other users are reporting something like this, so i guess it's some weird stuff you did on your phone that slows it down big time.

About the vmlinux binary, now it'a bit of a mess to recreate it: i had to reset back to an "old" state on my local repo to compile this kernel and now i switched back to head to keep developing, so please if you really want to profile it (which could be cool anyway) compile it yourself ;)

[LG Optimus 2x] Custom40:
Really?

Can't see how stability can increase any more than today. Seems like you have reached the top of the mountain.

OCing? Never used it and never will find it the need to.

Battery consumption? Simply a beauty to look at the batter percentage through usage - Can't see how that should improve any more either.

Both WiFi reception and battery usage when using WiFi can't be complained about.

HDMI? Really? Pff, please. HDMI is used once a year and can be replaced by a memory card haha.

Incoming/outgoing calls? Volume could be higher as its pretty low sometimes. Not the biggest issue, though.

No bugs, no shutdowns/reboots. Kernel is as smooth as a smoothie.

Perfection has been reached, kick back and relax.

Enjoy the kernel as it is.

Hey hey :)

Need to fix the brightness bug on ics though, that one is a deal breaker... and also would love to implement a better auto-brightness system for CM based roms. I think stability is reached, but "fully working" means having on all OSs the same level of options and usability. I could drop ics as a supported platform and be happy with what we have, but i don't know yet...

So when your phone is not stuck you use a program like Lumberjack to extract it. When it BSODed or so you connect it to a PC and extract it using adb. Here is how:
