We've been seeing a lot of similar bugs in Fedora since we pushed
a 2.6.38.8 update. Some of the traces are different, but some
look to be the same as yours. (here's one for eg: https://bugzilla.redhat.com/show_bug.cgi?id=712830)

The common cause seems to be 'device went away'. So USB CD drives,
USB memory sticks, and for some reason virtualbox shutdown.
