GPU crash dump

While I was playing video in mpv and simultaneously browsing web in chromium my
desktop stuck for a few seconds. The content of dmesg told me to report this
bug. 

[15961.655448] [drm] stuck on render ring
[15961.656284] [drm] GPU HANG: ecode 0:0xf5fffffe, in mpv [4446], reason: Ring
hung, action: reset
[15961.656286] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[15961.656288] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[15961.656289] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[15961.656290] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
[15961.656292] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[15963.655165] [drm] Enabling RC6 states: RC6 on, RC6p on, RC6pp off


I'm using Gentoo with 3.15.3 vanilla kernel, xorg-server 1.15.0,
xf86-video-intel 2.21.15 and mpv 0.3.10.
