The riser card must not be very active as the device(s) are sitting on bus #0, that means no PCI-PCI bridge.
BTW: REQ/GraNT lines are not a problem and probably that's what the manufacturer considers "active". IDSEL lines may be a problem (they define device#, must not clash with other devices, and it would be nice if the BIOS recognized them). IRQ lines are usually the main problem.
OTOH I wonder if we should make it possible to force IRQs on per-device basis? Or is it already possible? -- Krzysztof Halasa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
