  Log:
  If we get a stray interrupt, return after logging it.  In the extremely
  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.
