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

Andrew Hayzen, the next step is to fully reverse commit bisect from
kernel 3.16 to 3.18-rc7 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:
  Random freeze of UI and input for ~30s

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Description:	Ubuntu 14.10
  Release:	14.10
  Linux andy-Pangolin-Performance 3.16.0-25-generic #33-Ubuntu SMP Tue Nov 4 12:06:54 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

  This has happened a few times, the UI freezes and no input works for
  ~30s and then something resets/releases, all the inputs are then run
  and everything appears to be normal again.

  Note I did have Firefox nightly and icedtea-7-plugin installed (not
  sure if related to the freezes but these are the only things I have
  installed recently since the freezes have been occurring)

  The output of dmesg [0] also suggests a similar/or the same issue as
  [1]
