>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.

 Hi Ilmar,
 
 I'm pretty sure this problem was fixed in 3.2-RELEASE. Could you try
 with a more recent version of FreeBSD and let us know?
 
 Thanks,
 Sheldon.

 I've just installed 3.2 release. run some tests and couldn't reproduce
 this error. Maybe you are right and it was fixed. Anyway i'm sorry, i've
 just found and traced this error two weeks ago. If the problem still exist
 i'll let you know.
