I have the following SCSI devices in my box.

scsi id 0  Seagate ST-32550N (fast SCSI hd)
scsi id 2  Seagate ST-15150N (fast SCSI hd)
scsi id 6  Pioneer DR-U12X (CD-ROM)

The SCSI host adapter is Diamond FirePort 20 (NCR 875j).

The source tree was cvsupped on 19 Sept. ncr.c was of v1.129.

The kernel with CAM support didn't boot.  It printed the following
error messages (I noted the messages by hand).

ncr0: restart (scsi reset)
(probe6:ncr0:6:0) INQUIERY. CDB: 12 1 80 ff 0
(probe6:ncr0:6:0) ILLEGAL REQUEST asc:24,0
(probe6:ncr0:6:0) Invalid field in CDB
ncr0: timeout nccb = f07bd200 (skip)
...(lots of timeout messages)

I turned off the CD-ROM drive and restarted the machine in vain.
I got:

ncr0:2: ERRROR (a0:0) (7-a3-2) (e0/5) @ (mem a00001ac:a00001ac)
ncr0: regdump da 10 80 05 47 e0 00 0f 01 07 82 a3 80 00 03 00
ncr0: restart (fatal error)
(probe2:ncr0:0:2:0) COMMAND FAILED (9 ff) @ f07bda00
(probe2:ncr0:0:0:0) COMMAND FAILED (9 2) @ f07bde00

I just cvsupped again. ncr.c is now up to date; it's v1.132.
This time the kernel panics:

Fatal trap 12: page fault while in kernel mode.
fault virtual address: 0x0
...
_ncr_script_copy_and_bind + 0x46: movl %esi,0(%ebx,%edi,1)

Any ideas?
