Title:
  (docker/lxc) container restart causes kernel to lockup

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After restarting some 'ghost' docker containers on precise with the
  raring-lts kernel, the kernel locks up and shows:

      [1095015.392057] BUG: soft lockup - CPU#0 stuck for 22s! [gunicorn:12804]
      ... (for each core)

  Here is the original, more docker focused bug report:
  https://github.com/dotcloud/docker/issues/3873

  I could reproduce this bug with various kernel versions. I've set the
  softlockup_panic=1 kernel parameter to get some stack traces. See this
  gist for stack trace for 3.5 and 3.8 kernels (will add 3.11 any
  minute): https://gist.github.com/discordianfish/7886354d9a19b2084775

  It also contains a small script to reproduce this, although I couldn't
  reproduce it in a vagrant VM just our Dell R710 systems so far.
