    Ok, here's everything I got from the serial console when the error
    occurred. I don't have a clue how to interpret this stuff so I'd be
    eternally grateful if someone out there can help. Or, if I
    misunderstood what you were telling me I ought to do, then explaining
    the process a bit more would be appreciated too.
