Just look at APIC vs non-APIC. IRQ11 looks like non-APIC, IRQ16 is most likely APIC driven. If you have agp in your kernel, remove that line and preload the nvidia.ko from the bootloader. That way my system works with a 5900XT. (nforce2, no apic, acpi enabled) HendrikReceived on Wed May 05 2004 - 22:09:46 UTC
