This isn't the same problem... nobody else is reporting lockups AFAIK.

The skupping problem is known. Bump the priority of the mp3 player up a
bit and see if that helps.

Very probably. It sounds more like a SCSI problem than a sound one,
BICBW. Other people have been seeing problems with SCSI stuff recently,
but I haven't really been following it since my SCSI is very happy.
