[Ernst Martin Witte <1351353@xxxxxxxxxxxxxxxxxx>]

Hi all,

just to give some feedback on the 3.17 testing proposal: I'm also
affected by the bug reported here (no kvm, both with old and updated
BIOS) for 3.16.x utopic kernels, the problem "appeared" after short
uptimes of usually 1..2 day.

Now I'm running a 3.17 kernel without a crash for 14 days.

No idea if the bug is really fixed but the system usability has improved
significantly by the absence of such crashs ;-)

Please let me also express that I'd consider the importance of this bug
higher than medium since many Ultrabooks/Notebooks/etc. come with
embedded i915 graphics today.

BR and thanks!
  Martin

Title:
  Kernel oops

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  My system suddently became unresponsive so I tried to SysRq s/u/b and
  I think that's what caused another problem.

  Either way, my system hard-locked.
