You want to unmount /proc on shutdown (umount -a) and it's quite important that your machine not crash then (because otherwise your other filesystems won't get unmounted).
In general, even root shouldn't be able to cause a kernel Oops or machine lockup without doing something particularly evil (writing to /dev/ioport and loading duff kernel modules are two obvious examples).
