    SubjectRe: [patches] [patch 3/5] x86: Add PCI extended config space access for AMD Barcelona

    Examples? I can only think of PCI express error reporting, which
    few drivers implement anyways and isn't really a show stopper
    if it doesn't work. Besides I would be surprised if it even works
    on the cheap desktop boards which have MCFG less BIOS.

    How so?

    We only put in workarounds if there is a serious problem otherwise (e.g. not
    booting etc.). I just don't see this here.
