I think this should fix it for you. If for some reason your drive times
out (and is detected as a tagged queuing device), try disabling the
tagged queuing support. Its just a couple #if 0's in i386/scsi/aic7xxx.c's
ahc_done routine where it looks at the inquiry data to see if the drive
can do tagged queueing.
