/sys/class/drm/card0/error
I am experiencing hangs while browsing on the new WebGL version of Google Maps
or even browsing <a href="http://get.webgl.org/">http://get.webgl.org/</a> using Chromium. Versions involved are:
xorg-server: 1.15.1
xf86-video-intel: 2.99.911
mesa: 10.1.3
chromium: 34.0.1847.132
dmesg reads:
[ 254.743750] [drm:ring_stuck] *ERROR* Kicking stuck wait on render ring
[ 254.743758] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 254.743760] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 254.743761] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 254.743762] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 254.743763] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.

I also get a backtrace in my journal:
