[12731.764926] [drm] stuck on render ring
[12731.765818] [drm] GPU HANG: ecode 0:0x005f6256, in X [362], reason: Ring hung, action: reset
While playing a vido using mpv on a up-to-date Archlinux, my X.org freezed for maybe 10 seconds.
Attached the GPU crash dump, as suggested in the dmesg:

[12731.765823] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[12731.765826] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[12731.765828] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[12731.765831] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.
[12731.765833] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[12733.764905] [drm] Enabling RC6 states: RC6 on, RC6p off, RC6pp off

That looks like the mesa bug, and should be fixed by latest stable mesa release (10.2 or 10.1.5).
