Yep. ID 20, INT D (chipset POV). > EXT-PCI slot 2 (Upper slot) uses device 19 and INT_A. Right. > Upper slot has the problems.

So if ALNKA is INTA both PCI cards should > share IRQ 20? No. I don't exactly know what these ACPI messages show. Probably they list some power-up state, before devices are configured. If lspci says DN20 uses IRQ 20 and DN19 "uses" IRQ16 then that's exactly what they should use - two different INT/IRQ signals. If the lspci shows that DN20 uses the same IRQ as IEEE1394 controller and that DN19 uses the same IRQ as on-board Ethernet and VGA then that means just that: they share INTs/IRQs (this is especially true when running in IO-APIC mode). If lspci shows no IRQ for the device then that DN is not supported by the BIOS. I'd try this "aluminum film" trick. Just be careful, shorting wrong traces can destroy the hardware. As I wrote, shorting the good ones can make the system (temporarily) unusable. -- Krzysztof Halasa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
