>Environment:
Celeron-366(412)Mhz, 64 Mb RAM, 3.2 Gb HDD Seagate Medalist IDE,
		MB GA-6BXC - simple home pc.

>Description:
		While shutdown(rebooting) mount_mfs dumps core(while unmount 
		or exit?). That leads to panic("vinvalbuf: dirty bufs") while
		unmounting root.

>How-To-Repeat:
		Simply use the following fstab and maybe slow HDD (as 
		seagate is):
		
# Device		Mountpoint	FStype	Options		Dump	Pass#
/dev/wd0s2b		none		swap	sw		0	0
/dev/wd0s2a		/		ufs	rw		1	1
/dev/wd0s2b		/tmp		mfs	rw		0	0
/dev/wd0s2f		/usr		ufs	rw		2	2
/dev/wd0s2e		/var		ufs	rw		2	2
/dev/wcd0c		/mnt/cdrom	cd9660	ro,noauto	0	0
proc			/proc		procfs	rw		0	0

		mfs is the third. When i use it after all other fs - all seems
		to work fine.
	

>Fix:
I don't understand kernel problem. That is my question. But if you
	put mfs mount string after all others fs - it will be ok.
