Title:
  System crash Xubuntu 14.10 on i5-3337U CPU

Status in xserver-xorg-video-intel package in Ubuntu:
  Expired

Bug description:
  System is not running stable, it crashes (freezes) sooner or later.
  Sometimes with virtual console on screen, saying

  “not syncing: fatal exception in interrupt
  drm_kms_helper:: panic occurred, switching back to text console”

   - sometimes without console appearing. No more input possible (no
  sysrq), just hard reset.

   Apparently this is caused by i915 driver. It always happens with
  applications with a bit higher graphics performance requirements, e.g.
  watching DVB-T-TV in a little me-tv- or vlc-window and browsing the
  Internet at the same time. Initially core temperature and fan speed
  rise, and then follows the  exitus follows.

  Same experience on Xubuntu 14.04 and Kubuntu 14.04. The reason why i
  file this against Utopic is that i have altered my Trusty-Systems with
  Intel Drivers from 01.org (see below).

   The following attempts did not improve the thing:

   Trying “Intel Graphics Installer” from 01.org 1.0.7  within the
  Trusty Systems.

   Trying (alone and with Intel Drivers) Mainline Kernel 3.18.1. But of
  course initally with regular Utopic 3.16.

  It may be of interest that on the very same machine the OS “Siduction”
  (Debian Unstable Rolling Release) runs without any problems or
  concerns (currently Kernel 3.18 and xorg-packages from Debian Sid
  branch). The computer is the Asus "Vivopc VM-60", CPU  i5-3337U.
