Title:
  Intel Display i915 driver crashes, Thinkpad X1 carbon Gen 3

Status in xf86-video-intel:
  Fix Released
Status in xserver-xorg-video-intel package in Ubuntu:
  Incomplete

Bug description:
  
  - start ubuntu 15.04 and log in
  - use CTRL+AL+F2 to switch to TTY2. (or a different TTY)
  - Watch the screen glitch: http://youtu.be/MqPi5dURZ8s
  - sometimes it's so bad it will not recover and the computer needs to be forcefully rebooted.

  I should note this is on the newst generation Thinkpad X1 Carbon (Gen
  3)

  It generates this in dmesg:
