Daniel, This crash looks a LOT like one I was seeing while testing
Soren's recent ATA patches on my laptop, although the last set of
patches did not cause the crash. In any case, it looks a lot like an
ATA problem.

Please send-pr this and/or cc: Soren (sos@freebsd.dk) as I don't think
he reads the stable list.
