rare case of a stray interrupt to an unregistered source (such as a stray interrupt from the 8259As when using APIC), this could result in a page fault when it tried to walk the list of interrupt handlers to execute INTR_FAST handlers. This bug was introduced with the intr_event changes, so it's not present in 5.x or 6.x. Submitted by: Mark Tinguely tinguely at casselton dot net
