    #14627 and this bug are duplicates.

    Bugs #14900, and #14728 look very suspiciously like they might be the
    same thing as well.

    I would be interested to see if commenting out:
    '#define USE_PCI_DMA_API 1' in drivers/char/agp/intel-agp.c fixes the
    problem for those bugs as well.

    I suspect that some better run time checking is called for here.
