the SMP code is involved here...

looks like someone is using the (-1), ie ERROR result, as an IRQ value.
This is returned by the SMP code that converts the redirected PCI IRQs
to real APIC IRQs.  Is this a PCI card, or is other breakage involved?
My guess is that some plug-n-pray code is crossing paths with SMP code.
