>Release:        FreeBSD 2.2.7-RELEASE i386
>Environment:
	FreeBSD 2.2.7-RELEASE i386 with optical disk driver

>Description:
	disklabel(8) core dumped with optical disk driver if disktype was
	specified 'auto'.

>How-To-Repeat:
	Modifiy the kernel to support optical disks.
	optical disk driver patch set is distributed in following URL.
	ftp://jaz.jp.freebsd.org/pub/FreeBSD-jp/OD/od-driver-2.2.7R.tar.gz

	Then write the disklabel to a optical disk as following
	# disklabel -r -w -B od0 auto

>Fix:
	I have modified the function getvirginlabel() in disklabel.c as in
	freebsd-current, not to use lab.d_boot0.

	Patch is following
