I have recently upgraded to a Asus Pentium PRO Motherboard with their 
NCR810 SCSI controller. While using the Amanda backup programme I am 
getting a large number of errors from the controller. 

They are of the form.

Nov  5 11:51:35 hawk /kernel: ncr?: scatter/gather failed (residue=493925376).
Nov  5 11:51:35 hawk /kernel: sd0: oops not queued

They only seem to happen when it is backing up partitions other than 
the root partition. 

I have tried putting the Tape drive on a second controller but it made 
no difference. I did not have this problem with my GigaByte Neptune 
board using their NCR810 controller. 

Any ideas what is wrong.
