>Description:
This is something I saw with NetBSD 1.6.1 on my MTRON SSD w/ACARD SCSI to IDE 
adapter.  Recently 5.0 was made to work again on Atari and so I've now tested 
there with the same results.

This issue doesn't happen immediately, but once it happens it seems to take out 
the system pretty quickly.  That kind of makes sense, being that it affects 
disk operations.

The following screenshot shows the problem during an install of 5.0 RC2:

There are no other devices on my SCSI bus, just the MTRON/ACARD combo.
>How-To-Repeat:
Attempt to install/use NetBSD 5.0 RC2 on an ACARD SCSI to IDE bridge with an 
MTRON IDE SSD attached.  More info on the exact hardware specs can be provided 
upon request.

After a while, you'll see various messages from the kernel reporting "Check 
Condition on CDB", some #s, "SENSE KEY:  Illegal Request" and "ASC/ASCQ:  
Invalid Command Operation Code"
>Fix:
I do not experience this problem with a standalone Seagate SCSI drive.  I have 
no reason to believe that the MTRON/ACARD hardware is faulty in any way, I 
haven't experienced any problems using it with a PC and Adaptec SCSI controller 
(though not with NetBSD).
