In xnintr_attach(), the crash occurs in xnarch_set_irq_affinity(). If the
call is removed, the driver works as expected (gaining another 3 usec of
latency). Now investigating ipipe_set_irq_affinity.

We have a driver that operates on a PCIe card. The card has IRQ17. If we use
it like that (IO-APIC-fasteoi), interrupt registration using
rtdm_irq_request works correctly. (We also use rtdm_irq_enable afterwards,
but it seems that the request already enables the interrupt.)
However, if we redefine
