dmesg log (cut)

Hello,

I'm using Arch Linux and experience these GPU hangs occassionally (usually when using firefox) at least once a week since I updated from 3.11-something to 4.2.5-1-ARCH. I also tried the lts Kernel 4.1.12-1 which has got the same problem.
As a result, some windows are messed up (like a hurrican went through my desktop); some windows are not affected at all. Usually, firefox is affected and especially video playback stays messed up - but I don't know how helpful that is.

I have not tested the nightly build (I just read about it) so I'm sorry for that... I have prepared everything following the instructions of 'dmesg' which are a lot different... I will read through the instructions and add the logs and debugs ASAP.
