>Environment:

	ASI ASUS-PCI/I-P55TP4XE Motherboard, 256k p/b cache
	32MB RAM
	ASUS-SC-200 NCR SCSI
	Two DEC 512mb SCSI disks

>Description:

	syncing disks ... done
	Fatal trap #12: page fault while in kernel mode
	....

	Occurs at system shutdown. 100% repeatable.

	Seems to be related to use of MFS for /tmp
$ grep mfs /etc/fstab
/dev/sd1b               /tmp                    mfs     rw 0 0

	At least it didn't occur until I started using MFS.

	Have crash dump, though 'gdb -k' doesn't seem to be able
	to reconise the traceback info.

>How-To-Repeat:

	Use MFS /tmp, shutdown
