I'm having a few problems after installing an NCR 53c810 host adaptor with
a Quantum ATLAS SCSI drive and a Sony SCSI CD-ROM.  Basically, I have
the following messages on the console :

cd0(ncr0:3:0): copy aborted, data = 89 6d 40 24 02 01 03 fd 1a 60 f6 18 b9 68 17
 1c 80 18 44 70 32 4d 00 00 01 01 08 0a 00 00 00 00 00 00 00 00 00 08 00 00 00 0
 0 00 00
sd0(ncr0:0:0): copy aborted, data = 89 6d 40 24 02 01 03 fd 1a 60 f6 18 b9 68 17
  1c 80 18 44 70 32 4d 00 00 01 01 08 0a 00 1e 00 00 00 01 00 00 00 08 00 00 00 0 0 00 00

The SCSI bus is correctly terminated; I also have Termination Power enabled
on the SCSI drive.  I find that after these messages on the console, any
further operations fail (including mount) with 'copy aborted'.  
To get to this state, I found that newfs'ing the last partition on the 
SCSI drive causes this.  

I am using the same paramters for the disktab entry as is reported by the
kernel.  Does anyone know why this is happening ?  Is it a SCSI driver problem?

Hardware: Pentium 90, ASUS NCR 53c810 PCI SCSI adaptor, 
		Quantum ATLAS SCSI-2 drive, Sony SCSI CD-ROM.
		   
/etc/disktab entry:

quant21g|Quantum 2.1G: \
        :ty=SCSI:dt=SCSI:se#512:nt#10:ns#107:nc#3907:rm#7200:\
		:pa#2508294:oa#0:ba#4096:fa#512:ta=4.2BSD:      \
		:pc#4180490:oc#0:                               \
		:ph#1672196:oh#2508294:bh#4096:fh#512:th=4.2BSD:


I'd like to be able to recover from this state without rebooting.  Is there
any way ?


Any help _greatly_ appreciated.
