GPU crash dump from /sys/class/drm/card0/error

During using the Google Chrome on Ubuntu 14.04/64 I often experience this
error:

Aug 12 03:28:56 * kernel: [105286.318002] [drm:ring_stuck] *ERROR* Kicking
stuck semaphore on render ring
Aug 12 03:28:56 * kernel: [105286.318007] [drm] GPU crash dump saved to
/sys/class/drm/card0/error
Aug 12 03:28:56 * kernel: [105286.318008] [drm] GPU hangs can indicate a bug
anywhere in the entire gfx stack, including userspace.
Aug 12 03:28:56 * kernel: [105286.318009] [drm] Please file a _new_ bug report
on bugs.freedesktop.org against DRI -> DRM/Intel
Aug 12 03:28:56 * kernel: [105286.318010] [drm] drm/i915 developers can then
reassign to the right component if it's not a kernel issue.
Aug 12 03:28:56 * kernel: [105286.318010] [drm] The gpu crash dump is required
to analyze gpu hangs, so please always attach it.

Doing as suggested: filing new bug.

Mostly this appears after heavy Adobe/Pepper flash usage, but not always.
