Perhaps a spurious interrupt is being thrown, or an interrupt is routed to the wrong processor. (Is the behavior of a HLTed processor that gets a misrouted interrupt different than that of a processor that is polling?) There certainly seems to be a timing sensitivity too. Is there a kernel mode sleep-like function that I could play with?
