Oooh, that actually isn't that strange. If you have a serial console the
interrupt delievery system gets update on a regular "hearbeat" - even if you
are not typing anything. On my Xyplex it keeps on sending empty characters even
if I am not typing anything.

Does it happen if you do 'poweroff -h -f' (that is a heavy handed way of
shutting the machine where it does not even sync - so make sure you mount your
drivers RO before you do this).

Does reboot work reliably?
