This may be a strange question, but you don't happen to have and RZ57 
attached to that SCSI channel do you? This may not be related at all but I 
know that in the VAX port an RZ57 will hang the bus during the initial 
probe. There has been speculation that this is due to a lack of a 'start 
unit' command and bogus firmware on the drive that fails to complete an 
INQUIRY when it isn't spinning but I've never had the patience to actually 
dig down and figure out what was going on.
