It isn't just a debugging facility. It is still beneficial to the end user
in that it restarts the system if there is a bus lockup or a faulty
interrupt
handler in a rarely used codepath. This is better than the alternative
of draining
the battery and turning off. We want this to be turned on independent of
what userspace
one is using, unless they explicitly turn it off themselves.
