>Description:
When I tried to replay a music CD with xmcd 2.1 under a 961210 kernel
I got these messages:

cd0(ncr0:2:0): asynchronos
ncr0: timeout ccb=0xf87dc800 (skip)
ncr0: timeout ccb=0xf87d9200 (skip)
ncr0:2: ERROR (80:4) (9-0-0) (e0/13) @ (d8c:19000014).
        script cmd = 89030000
        reg:     da 00 80 13 47 e0 02 1f 01 09 82 00 80 00 09 02.

And after that the SCSI bus was completely locked. I looked at our local
SUP mirror, found that "ncr.c" was changed recently, updated my sources
and recompiled the kernel. But the problem remained.

I use an ASUS SC 200 (NCR 53c810) and a Toshiba 5201. "xmcd" worked fine
with both with earlier version of the NCR driver.

>How-To-Repeat:
Try to use "xmcd" with a SCSI CD-ROM drive connected to a NCR hostadapter.

>Fix:
Sorry, I'm not a SCSI expert.
