Or are you saying an NMI in an idle system will have the same %rip thus falsely detecting a back-to-back NMI?
That's easy to avoid - insert an instruction zeroing the last nmi_rip somewhere before or after hlt. It's always okay to execute such an instruction (outside the nmi handler itself), since nmi_rip is meant to detect a "no instructions executed" condition.
