Title:
  GPU hang after running gpu_test (designed to lockup the GPU)

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  [Update] It's not a regression and does not seem to be a kernel bug.

  [Update] also affects a Dell Latitude E6220 system with the same
  -proposed kernel, sounds like a regression.

  When running the Certification SRU tests (Checkbox gpu_test script)
  for the -proposed 3.5.0-36.57~precise1 on a HP ENVY Pavilion dv6 with
  an 'Intel Corporation 2nd Generation Core Processor Family Integrated
  Graphics Controller', after the script is finished running the
  message: GPU hung Detected appears.

  In syslog, I can see:
