Just to clarify -- the interrupts are scheduled to arrive at a specific
CPU for the APIC case. The code is supposed to do a round-robin
selection, but I don't think that code is working. You can enforce that
interrupts arrive at a specific CPU by manually changing the right field
when the interrupt is currently not routed. There is no API for that
