Well, at the very least my presumption about mailbox register 2 containing
the ordinal bus where resets are detected even for 1040 f/w is wrong
(ambiguous Qlogic documents- for dual channel controllers an async event
like a bus reset has to say for which bus the reset happened- but I guess 
Qlogic pooched it and just didn't make this generally true for all hbas..)
but that's pettifoggery..

Ow. I think this is very likely due to the bug in isp_netbsd.c that didn't
get checked in until 12/5. I sent you (under separate email) a ALPHA
kernel from this morning. See if that helps.
