Your interrupt routing table looks pretty strange to me.  I'd try:


and see how that works.  Maybe try different values in place of 11.
The thing I don't understand is why your dump_pirq output shows all
PCI interrupt pins as "unrouted":

> Interrupt router at 00:12.0: Intel 82371AB PIIX4/PIIX4E PCI-to-ISA bridge
>   PIRQ1 (link 0x60): unrouted
>   PIRQ2 (link 0x61): unrouted
>   PIRQ3 (link 0x62): unrouted
>   PIRQ4 (link 0x63): unrouted
>   Serial IRQ: [disabled] [quiet] [frame=21] [pulse=4]

This makes me think my suggestion is unlikely to work, because PCI
interrupts are not being routed in a way that I understand.

But this is an SMP box so maybe this is an IO APIC issue, and the
interrupt routing table doesn't apply.  In that case this is over my
head: maybe contact Martin Mares <> and ask him how to figure
out or fix the interrupt assignment for a PCI device on an SMP box
when the BIOS doesn't fill in the PCI interrupt line register.  He may
tell you that this combination won't work with a 2.2 kernel.
