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.
