I got this and made a new kernel with not much change to the whole mess. 
This time I get COMMAND FAILURE (9 0) showing up a few times (I have 
seen this before), I get hard wedges (I did an fsck to batter the SCSI 
driver a bit and have not made it through one fsck yet alive without 
either a command failure or just a lock up - the drive light jams on 
solid and nothing ...), and a couple of parity errors reported. This 
last is a new trick - I have never seen this one before in the couple of 
years that I have been running the driver (a new message?)

I talked to my supplier and have got another SC-200 on loan from them. 
This one's NCR chip is badged a SymBIOS 510A. The new kernel is 
reporting my current card as a 510 only, so there are subtle differences 
already, I think. I am really looking forward to trying this one out and 
seeing if the problem is solved. If it is, there could be a chip problem 
as someone suggested.

Anyone else out there running NCR cards with the new kernel getting a 
straight 510 reported? What type of card? I am still collecting info 
about NCR configurations that do/don't work - thanks to all who have 
sent in stuff so far.

Let you know tomorrow - time to go home now.
