>Release:        FreeBSD 2.1.0-Development i386
>Environment:

	950322-SNAP, NCR810 SCSI
	The drive is "SONY CD-ROM CDU-8012 3.1a", which is an old
	Sun external CDROM box.

>Description:

	Ejecting the CD in xcdplayer (using the eject control
	in the program) sometimes causes a timeout (or so I infer),
	followed by a scsi reset that doesn't quite recover.
	At this point, the machine dies with all scsi commands failing.
	One consequence is the inability to sync before reboot.
	Another is not being able to switch to ttyv0 (if any paging
	of the X server is involved) and see the error messages.

	The problem is most likely not caused by xcdplayer itself.

>How-To-Repeat:

	xcdplayer
	click on the eject box
	wait

>Fix:
	
	If someone wants to debug this, I can try to repeat and
	get the kernel messages and some more data.
	As it is, since it's a particularly nasty crash, I don't
	want to mess with it too much.  I did try it twice to make
	sure it wasn't a fluke.
