Hrmmmm ... I have no internal SCSI disks at all. Unless we count the
CDROM which seems to work just fine. I did discover over lost hours
that one must use CD-R media and *not* CD-RW. The old CDROM works
fine with the CD-R stuff if the burn is very very slow.

Well here I am at a loss because I am using an external Sun SCSI storage
array which may be old but it is a battle axe. Works flawlessly on every
machine I ever tried and that includes this DEC AlphaStation 600. Just
not with the NetBSD isp driver.

Looking in sys/dev/ic/isp/isp.c where I know we need to deal with an
error etype at line 5279. However, I can not handle the error which
seems to be unknown and we fell into the default :

        default:
            isp_print_bytes(isp, "Unhandled Response Type", QENTRY_LEN, 
qe);
            if (XS_NOERR(xs)) {
                XS_SETERR(xs, HBA_BOTCH);
            }
            break;

So then wherefore do we get this isp0: Unhandled Response Type 0x9 ?

This all starts with the LeeLoo Dallas "Multi-Pass" at line 5053 :

    buddaboom = req_status_flags = req_state_flags = 0;


Clearly, yes ..... big buddaboom. Big.

I would need to make this verbose as hell and rebuild isp and see what
sort of really Big Budda Boom noises are made.
