  Incomplete

Bug description:
  I have an application that uses WebGL in chrome browser. Unfortunately
  from time to time graphics drivers crashes:

  [ 9455.632427] [drm] stuck on render ring
  [ 9455.633536] [drm] GPU HANG: ecode 7:0:0x86d2fffd, in chrome [1584], 
reason: Ring hung, action: reset
  [ 9455.633539] [drm] GPU hangs can indicate a bug anywhere in the entire gfx 
stack, including userspace.
  [ 9455.633541] [drm] Please file a _new_ bug report on bugs.freedesktop.org 
against DRI -> DRM/Intel
  [ 9455.633543] [drm] drm/i915 developers can then reassign to the right 
component if it's not a kernel issue.
  [ 9455.633544] [drm] The gpu crash dump is required to analyze gpu hangs, so 
please always attach it.
  [ 9455.633546] [drm] GPU crash dump saved to /sys/class/drm/card0/error
