ACK, of course, but this brings up something else: what's the status of
moving chip reset outside of a spinlock?
Currently a reset during operation can trigger the CPU lockup detector
and other doo-dads, because you can easily spend a second or two with a
spinlock held (a loooooong time, to hold a spinlock)
