On a SuperMicro motherboard, NCR825 SCSI, 1 gig wide SCSI drive
and a default kernel from both the 2.1.0 CD and the 2.2-960501-SNAP
CD I get the following:

changing root device to sd0a
de0: enabling AUI port
(very long pause)
ncr0: aborting job ...
ncr0:2: ERROR (90:0) (8-0-0) (0/13) @ (a54:50000000).
        script cmd = 740a8700
	reg:     de 00 00 13 47 00 0f 0f 35 08 81 00 90 00 0f 02.
ncr0: restart (fatal error).
sd0(ncr0:0:0): COMMAND FAILED (9 ff) @f0c30a00.
sd0(ncr0:0:0): WIDE SCSI (16 bit) enabled.
sd0(ncr0:0:0): FAST SCSI-2 100ns (10 Mb/sec) offset 8.
sd1(ncr0:1:0): FAST SCSI-2 100ns (10 Mb/sec) offset 8.

Only once did this cause problems because the install program
said it couldn't see the CD.  Rebooting fixed this.

When I install a custom kernel with all of the unnecessary drivers
removed, this error doesn't occur.  Also, for either case, the
system will stay up for days with no problems.
