I've been having trouble with hardware errors on one disk drive causing a
filesystem panic that appears to force the filesystem into read-only mode
but the processes accessing it are blocked and won't die from signals.
I would like to be able to force a reboot remotely when this happens but
even 'reboot -f' hangs. Is there some other way besides punching the reset
button to make the machine restart?
