This is stranger than I thought.

Trace says sbp2_abort was called from sbp2_free, called from sbpscsi_match.

In sbp2_abort, the parameter orb seems to have pointers to bogus data:
&orb->sbp2 = 0xc0fd801c
&orb->sbp2->orbs = 0xdeadbf33

This suggests that orb->sbp2 is very close to 0xdeadbeef - which shouldn't
happen.  I have checked every point at which a new orb is allocated in sbp2.c,
and none of them seem to be forgetting to initialize it...

Just my luck this should turn up on the day when I have a drive failure and
need to use an external drive right this minute.
