This is with FreeBSD-2.1 as client and a Netware (NFS) server. I believe the
handle is stale (They changed disks without telling us beforehand), but I
cannot get it unmounted, not even with umount -f which I would have thought
should force it. At the moment it looks like I will have to reboot the
FreeBSD machines to clear the problem.

The HP machines which also mounted the Netware server, could unmount
it with the force option.
