Title:
  Error in i915 driver

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  The 7th of september I lost my Xorg display on wily. I was always in failsafe mode.
  I still could get openbox to run, which was still loading i915, but didn't consume any 3D/advanced instruction I thinK.
  I didn't got too much time to go beyond. 

  As I got also a btrfs kernel dump message, so I checked my ram at
  least with memtest86+, all was OK.

  Reverting to vivid allowed me to be back on unity.

  Wily-amd64, kernel 4.2.0.7-7-generic/low-latency

  Here are the traces I got:
