	FreeBSD has 2 buffers remaining.
>How-To-Repeat:

	fsck -f /dev/sda1
	fsck -f /dev/sda2

	boot FreeBSD 6.0-BETA2
	mount -r -t ext2fs /dev/da0s1 /mnt
	reboot
	Syncing disks, buffers remaining... 2 2 2 2 ...
	Giving up on 2 buffers

	boot Linux
	fsck /dev/sda1
	/dev/sda1 was not cleanly unmounted, check forced.
