No thanks, probably. :-) The workaround is known.

BTW, you should PLEASE PLEASE explicitly negotiate async mode if you
want to do that, e.g. when sbic_inhibit_sync = 0. AFAIK, the sbic
hardware doesn't have any means to reset the scsibus without resetting
all the mainboard, so the first async transfer on the bus will lock up
the machine, too.
