mounting a nfs volume results in a kernel oops / no rebooting possible
anymore (hard reset...)

[2.]
i've mounted a partition on my server with nfs, the connection was
'lost', i don't know, however i couldn't access the files anymore.
after unmounting the volume, i tried to mount them again, mount blocks
(no effect with kill -9). I found a kernel oops related to running
mount. Rebooting was not possible anymore, i had to do a hard reset.
The fileserver has an uptime over 92 days, the bugged system an uptime
over 9 days.
