>Description:
	When I ran tar to extract many files on LFS partition,
	kernel panic was occurred.
	
	panic: kernel diagnostic assertion "vers > 0" failed: file "/usr/src/sys/ufs/lfs/lfs_segment.c", line 2674
	Stopped in pid 6.1 (ioflush) at netbsd:cpu_Debugger+0x4:        popl    %ebp

>How-To-Repeat:
	Extract all NetBSD release files on LFS partition:

	# tar xzvpf /var/pub/NetBSD/binary/sets/*.tgz
