        I don't know with certainty, but it looks like a selftest
        on an Intel i860 failed.  I believe this was used as the
        CPU for some graphics adapters.  Whether it was the i860
        that failed, or something between it and host is probably
        the more interesting question.  One message suggests a
        host timeout on a DMA read from the i860 and the other
        suggests the i860 didn't start running.

        Some of the middle-high-end graphics adapters we sold
        with the DECstation families used Intel i860s as CPU
        in the graphics adapters.  There is much more to the
        adapters than just the CPU.  Some even used a pair of
        CPUs.  I'm simply being precise.

        I don't know enough about the hardware to tell if it
        is the graphics CPU that is bad or something between
        graphics CPU and the host.  If the system's on a service
        contract, call field service.
