     It seems to be P4-based -- I'm pretty sure the integrated APIC behaves
    the same way regardless of where its plugged in, so why wouldn't this
    problem appear earlier? I've browsed my mailbox and found a patch that
    was stated to fix problems on the system involved. But the patch disables
    the timer around certain actions -- that may indeed matter for some broken
    firmware (especially some SMM crap), but I can't see how these bits could.

     That doesn't of course mean your patch shouldn't be applied -- it won't
    hurt to be overly careful.
