Hi everyone,

I use a INTEL D201GLY2A mainboard, and after serveral trys PCI devices were only useable (not visable) with the boot-parameter acpi=noirq (or noacpi). I tryed several kernel-versions (stated with 2.6.22), and no sucess without his parameter.
Without acpi=noirq all pci devices are deteced well, but if you want to use them, there is no response.

Do you have the latest BIOS on this board? Any nonstandard BIOS settings? It looks like the board is not using APIC but the ACPI IRQ information is giving out IRQs over 15, which doesn't make any sense. Maybe you're running in some kind of broken/untested BIOS configuration.


Yes, it was the latest BIOS for this board, but Intel put a new to the Internet these days. I updated the Bios, but no change at all.
There is only one ACPI-Relevant switch in the Bios, so I donÂt think that the Bios configuration is the problem. The only on ACPI-relevant option is:
"Resume from S5 by LAN". But I donÂt belive that this makes the problem (and I tryed both: on and off). There is no way to modify/reservate interrups in the Bios.

It looks like very buggy ACPI-tables in the Bios.
