    I can post a log, but:
       Interrupts are occuring, and being trapped.
    The following code in the driver just seems to always return
IRQ_NONE when called from an interrupt.
   
        int_status = c67x00_ll_hpi_status(c67x00);
        if (!int_status)
            return IRQ_NONE;

    However, if I add a timer that just polls the interrupt handler, I
have the driver working (on the first port) but slowly.
