This most likely indicates an incorrect PCI interrupt (IRQ) routing, and
you should try letting the kernel ACPI subsystem configure it:

Add the option "acpi=on" (although "pci=acpi" should suffice, you'd be
potentially missing other ACPI features) to your kernel boot parameters,
either via the GRUB boot menu or, for a permanent change, by appending
it to the appropriate "kernel" line in /boot/grub/grub.conf.
