looks like the following is happening:
the controller wants to send an irq (probably from previous life)
then suddenly the driver gets loaded
* which registers an irq handler
* which does pci_enable_device()
and .. the irq goes through.
the irq handler just is not yet expecting this irq, so
returns "uh dunno not mine"
the kernel then decides to disable the irq on the apic level
and then the driver DOES need an irq during init
... which never happens.
