when the process is in kernel space you cannot kill it because it is
protected, otherwise you could assert and crash the box. when a proc
is doing i/o it context switches into kernel space to the the i/o, you
cannot kill it when this happens.. as detailled above a reboot is the
answer in this case.

You should however work out why this pid is stuck doing i/o ? nfs hard
mount and the nfs server gone down ? faulty disk or adapter ? network
card issues / packets dropped etc.. if you fix the issue, then you
wont get into this situation.
