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....

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)

Thanks, i'll look into it. Just for curiosity, does this happen also with stock cm kernel ?

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!

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...

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

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 :/

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.

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 [email protected] under kernel, you only see numbers: 2.6.39.4.. This is normal and just fine, right? I'm on DM 1.4X...
Thanks again
