System: FreeBSD 4.4-STABLE #0: Thu Sep 20 19:58:56 KRAST
	ATAPI CD-ROM

>Description:
	It is impossible to mount CD-ROM in some cases.

>How-To-Repeat:
	1. Insert any CD-ROM into drive. 
	Make shure it can be mounted:
		
		# mount -t cd9660 /dev/acd0a /cdrom
		# umount /cdrom

	2. Now eject tray manually using 'eject' button of front panel of drive
	Then insert in back using command:
		
		# cdcontrol -f /dev/acd0a close
	
	3. Now it's impossible to mount CD-ROM:
		
		# mount -t cd9660 /dev/acd0a /cdrom
		cd9660: /dev/acd0a: Device busy

	You have to eject and reinsert CD manually to revive your drive.

>Fix:

	Unknown for me. This bug seems to be related with another one
	explained in http://www.FreeBSD.org/cgi/query-pr.cgi?pr=28166
