FreeBSD will fail while ACPI will have Active-High and Level-triggered, e= xcept if you define, as Aur=E9lien said, an "Extended Interrupt Descriptor" in = ACPI table. BTW, I'm not able to boot Debian Sarge (2.6.8-11-amd64-generic) with your= patch (as before). Moreover, I don't understand what this patch resolves...
