Title:
  Occasionally mouse cursor get stucked, internally i915 driver seems to
  be culprit

Status in xorg package in Ubuntu:
  Expired

Bug description:
  I documented my problem here:
  
http://askubuntu.com/questions/795970/lubuntu-14-04-mouse-cursor-stucks-occasionally

  tl;tr
  Mouse cursor stucks on certain events (clicking on Back-button in 
Chromium-brouser triggers it every time), and then in logs are following lines:

  [drm] stuck on render ring
  [drm] GPU crash dump saved to /sys/class/drm/card0/error
  [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, 
including userspace.
  [drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI -> 
DRM/Intel
  [drm] drm/i915 developers can then reassign to the right component if it's 
not a kernel issue.
  [drm] The gpu crash dump is required to analyze gpu hangs, so please always 
attach it.
  [drm:i915_set_reset_status] *ERROR* render ring hung inside bo (0x77d7000 ctx 
0) at 0x77d94a4
  [drm] GMBUS [i915 gmbus vga] timed out, falling back to bit banging on pin 2
