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.

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