    SubjectRe: lost interrupt hell - Plea for Help
    Date

    Yeah, the spurious interrupt does seem to be an AMD apic problem, but the lost
    interrupt (on ripping audio) seems to be a VIA chipset problem, as people
    with KT266 chipsets are having boot problems / audio rip problems regardless
    of the processor type. Lucky me, I get both ;)
