Answering yes, io_apic_one.c will be used, which is ((io_apic.c minus quirks) minus multi_io_apic_capability) . It'll propably crash some machines, as the quirks are there for some reason... With CONFIG_ONE_IOAPIC unset, you'll get the same kernel as with my previously sent patch. have fun :-) Karsten
