[Fede <922906@xxxxxxxxxxxxxxxxxx>]

I had this problem repeatedly even after this ticked was closed. So I
switched to Debian wheezy and never had the problem again.

Regards,
Fede

  SRU Justification:

  Impact:
  When plugging and unplugging a USB drive occasionally a race condition in the notify subsystem causes a kernel oops.

  Fix:
  A set up of patches 0520bffba9685d88ad68ede4a41abd08a3e9684e..fe9b25d3ee6bdf6f9c9a9ce61d9d3e144bac13ef found in the for-next branch in the notify.git tree solve this issue:
  http://git.infradead.org/users/eparis/notify.git/shortlog/refs/heads/for-next
  These have been cherry-picked and tested on precise/quantal and applied already to raring. Only small modifications are needed for 2 of the patches because the locations of the functions had changed other than that the other 7 patches are clean cherry-picks.

  Testcase:
  Comment #8 and #9 in the upstream bug: https://bugzilla.kernel.org/show_bug.cgi?id=22602 has a test case that easily reproduces this issue within 15-30 minutes. I have applied the above fixes and was able to run this test case overnight in all cases.
  In addition I've tested using the LTP tests for inotfy and these run properly with the fix applied.
