    It's somewhere in the scanning code. There's a case where it runs off
    the end of the stack. Check the compaq drivers for SATA as well, they
    also crash in a similiar place during bus scan. Both occurred during
    bootup, so I wasn't able to get a log of the particulars. Should be
    easy to reproduce. Compaq Presario 2200.
