Have you tried with ACPI? And conversely, if you're already using ACPI for
PCI irq routing, have you tried with "pci=noacpi"?

Basically, it looks like there is no irq routing information for the chip.
Which is deadly for any PCI device - we can figure out pretty much
everything else, but not the irq.

We don't ever try to autoprobe for PCI interrupts, because it's fragile
and tends to cause lockups on any hardware where the irq is shared with
something else. So PCI devices require irq routing information somewhere
(usually PIRQ table in the BIOS or the ACPI tables).
