I still cannot reproduce this here.  If it is very reproduceable
for you, perhaps you can modify ahc_search_qinfifo so that the
return from ahc_lookup_scb() is always tested for NULL.  In
the case of a NULL lookup, print the scb_index used for the
lookup, call ahc_dump_card_state(), and panic.  Perhaps with
that info I can figure out what is going on.
