Can you test the latest 3.11 upstream stable kernel[0]?  This will tell
us if the commit that introduced this regression in 3.12 was sent to
stable.  If that kernel tests out ok, we should test some of the 3.12
release candidates to find the first one that introduced this.

I have a feeling it may have been sent to stable since comment #4
suggests this is also in 3.5.

Title:
  kernel stack trace when running openvswitch DEP-8 tests

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  The DEP-8 test exercises the openvswitch userspace and kernel module
  by setting up to bridges, connecting 7 'hosts' to each bridge,
  patching the bridges together and then running performance and ping
  tests between hosts on different bridges.

  The stack trace occurs on teardown of the bridges/switches.
