1) One of the slots shares an IRQ with an on-board device, and the
drivers of the on-board device and the card you put in that slot can't
cooperate.

2) The two slots share an IRQ with each other, and the two devices
can't cooperate.

PCI IRQ sharing is generic and handled at the driver level. And
drivers for all PCI devices must handle this. So, either the slot or
the driver is likely broken.
