[ 1241.220427] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[ 1241.220429] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
[ 1241.220431] [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
[ 1241.220432] [drm] drm/i915 developers can then reassign to the right component if it's not a kernel issue.
[ 1241.220434] [drm] The gpu crash dump is required to analyze gpu hangs, so please always attach it.

Hence, could you please file a new report as noted, and post the URL of
your new report?

Title:
  8086:0a06 [Acer C720] Screen freeze during use of chrome/chromium

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I am using ubuntu 14.04 64-bit. (All my packages were up-to-date as of
  about 1 week ago.) My hardware is an Acer C720 (Intel graphics). The
  symptoms of the problem is the display completely stops updating,
  except the mouse cursor continues to move. Clicking and any keypresses
  have no effect. The system remains in this state for about 15-60
  seconds, then it recovers and goes back to normal.

  The problem most commonly happens when using chrome or chromium to do
  any kind of intesive hardware-accelerated rendering. Typically a
  youtube video or and HTML5 game with lots of animations. The problem
  tends to happen during periods of high CPU usage.
