Crash dump

> [ 1366.994426] [drm] GPU crash dump saved to /sys/class/drm/card0/error
> [ 1366.994428] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.

> [ 1366.994431] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

This happens about once or twice each game while playing Dota 2. The game hangs
for a few seconds and then crashes.

Crash happens regardless of texture quality, though on High it subjectively
appears to happen more often than with Low. However I cannot reproduce it
reliably, i.e. it will hang on seemingly random occasions.

gziped contents of /sys/class/drm/card0/error attached.

GPU is Iris™ Pro Graphics 5200 that comes together with Core™ i7-4750HQ.
