It doesn't look CIFS related right offhand. It crashed in some JBD
related routines (probably something ext3 related). I'd probably
suggest fscking the disks.

That said, it's sometimes very difficult to tell the root cause from an
oops message. You probably can't rule out CIFS altogether but it's not
where I'd go looking first.
