["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Max Bowsher, the next step is to fully reverse commit bisect from kernel
3.16 to 3.17.4 in order to identify the last bad commit, followed
immediately by the first good one. Once this commit has been identified,
then it may be reviewed as a candidate for backporting into your
release. Could you please do this following
https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F
?  Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.

Title:
  System lockups with utopic kernel

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Since upgrading to utopic, I've been experiencing occasional system
  lockups - when this occurs, nothing at all is responsive including the
  mouse pointer and Alt-SysRq combinations.

  Lockups only occur infrequently - perhaps once every day or two days -
  so testing this is going to be slow and problematic.

  So far, rolling back to the trusty kernel seems to have fixed it, so
  it seems unlikely to be a hardware problem.

  I'm going to reboot into http://kernel.ubuntu.com/~kernel-
  ppa/mainline/v3.17.4-vivid/ now and run with that for a few days.
