The controller should be terminated (probably 2 or 3 resistors, similar to
what's on the drive), and you should stick a terminator on the end of the
'last' centronics connector.  If the 'drive->out of case->centronics' cable
run is small, you can just terminate the drive instead.

Definately sounds like a termination problem, or a bad cable.  I was
schuffling drives around during the NetBSD install, and would get this same
error whenever I didn't take the time to terminate things properly. 
Although I usually got it from the prom, not from the kernel.  Sounds like
the same error though.
