I have a PC (550 MHZ P-III, Asus P3B-F, 256 MB) with two Adaptec 2940U2W boards with six IBM DMVS36V 36GB drives. I also have a four gig internal SCSI drive attached to the first 2940U2W to boot from. The goal is to use vinum and create a RAID5 system...

I get the following messages:
(da1:ahc0:0:1:0) SCB 0x0c - timed out in Data-out phase, SSEQADDR == 0x5d (da1:ahc0:0:1:0) BDR message in message buffer (da1:ahc0:0:1:0) SCB 0x0c - timed out in Data-out phase, SSEQADDR == 0x5e (da1:ahc0:0:1:0) BDR message in message buffer (da1:ahc0:0:1:0) no longer in timeout, status = 34b ahc0: Issued Channel A Bus Reset. 4 SCBs aborted
...
What gives? Anybody have any ideas?
I'd look very closely at the physical setup: particularly termination.
The Adaptec boards do autodetection for termination settings and suchlike; I've seen this cause trouble before. Drop into the Adaptec BIOS on boot using ^A and try setting the termination settings explicitly (internal and external) for both boards.
