Title:
  WARNING: at /build/buildd/linux-2.6.32/kernel/power/suspend_test.c:53
  suspend_test_finish+0x88/0x90()

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  Happend after waking up from suspend.
  The only obvious setback is that 3D apps stutter (low fps).

  My guess is:
  It is related to the multi-core cpu or the switching of cpu cores. 
  If I restrict the 3D apps to using only one cpu core the problem is gone.
