I was kindly pointed to this (excellent) report:
http://lists.freebsd.org/pipermail/freebsd-current/2009-August/010937.html

Gonzalo,
if you still have the crash dump or could readily produce it, could you please go
to frame #6 in kgdb and examine the following variables?
softc
ccb_h
ccb_h->target_id
softc->atadev[ccb_h->target_id]

If anyone else can do the same, it would be useful too.
Thank you!
