    Crashes as in seg faults in init?

    Are you getting any console errors or warnings at all?

    See if you can boot into single user mode and natacontrol ad0 to
    PIO4 mode or something like that.

    We're going to have to characterize the type of corruption that
    is occuring.  The DMA modes are definitely being set properly!
