>Originator: Ilmar S. Habibulin
>Release: FreeBSD 3.1-RELEASE i386
>Organization:
>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.
