[KERNEL] Camera fail

[umberto1978]

DEVICE: GT N7100 international

ISSUE: Camera fail only on some device, running a DMG1 (asian) custom rom.

Hi all. My compiled custom kernel causes a camera fail only on few devices, as stated above. Flashing some other kernel (like Adam for example) fixes the issue, than re-flashing my kernel the camera continue work.

Maybe related to the fix for exynos exploit included? I have no idea: why only on few devices (mine is ok) and not all?

HERE are my sources i am working on.

If anyone, willing to help, needs some other information i am here.

NOTE: At the moment my kernel does not support debug features (disabled on def_config) so no DMesg, but only android logcat. I will change the configuration as soon as possible and when available i will post dmesg here, if needed.

Are your sources based on sources of Perseus kernel?

Thanks for the interesting question!
No my sources are based upon update2 for note 2 from samsung osrc with some patch from some other developer, AndreiLux too.
Ehm...why?

Actually I cant recall who but someone reported same who tried building kernel from Andreilux git, may be Andreilux git soudce /note2 has some bug somewhere, not only you'd see camera fc but as well unable of video playback.

Would be useful to know more detail about this.
Anyway in my case scenario the camera is not force closing but the issue is a "camera error" warning (like a library issue i think).
Tomorrow i will build a version within debug features enabled, so i can investigate further.
Thanks for your reply.

Grab a logcat while opening the camera app

Grab a logcat while opening the camera app

This is a problem.
The person that is experiencing the issue (that its not me, i am not able to reproduce the error unfortunately) is not available.
I tried to contact him since yesterday but no responding at all. Damn....
As soon as he becames on line i will ask to reproduce error and grab both logcat and dmesg. Thank you anyway.
