  Random freeze of UI and input for ~30s

Status in linux package in Ubuntu:

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
