here are the errors from the messages log.  This ONLY happened when A) a
device was connected to the Adaptec 29160N and B) when the device was
being used by dump.  According the the replies I am afraid the problem may
be related to the MB..  And ideas on how to trouble shoot it?  For some
reason this error no longer occurs with the AHA-2940.  Could it be some
IRQ conflict?  I know that the SCSI controller used IRQ 11, as do alot of
the other devices on the system..
