Possibly this and other recent kernel BUGs and/or OOPses are due to the regression fixed by this:
https://lkml.org/lkml/2011/12/14/395
In which case they're dupes of this bug:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/903010
I'm re-testing with today's kernel, but don't know if those include the upstream patch yet.
