var/log/messages

Starting approximately a week ago, I experience system crashes during which the
system suddenly freezes and becomes completely unresponsive. The crashes are
random, and I would estimate them at a probability of one per hour.

They appear to take place while playing certain games: In my case I noticed
this with The Dark Mod (Doom 3 / idTech 4 engine). Although this is uncertain
and barely verified, using OpenGL 3.1 for KDE desktop compositing may also
provoke the crashes, whereas using OpenGL 2.0 does not.

My operating system is openSUSE Tumbleweed x64 (always latest packages). Kernel
4.8.4-1, Mesa 12.0.3, Gallium 0.4 on AMD PITCAIRN (DRM 2.46.0, LLVM 3.8.1). My
video card is a Radeon R7 370 Gigabyte. Attached are: var/log/messages (today
only), Xorg.log, xsession-errors. The last crash took place somewhere after
9PM.
