I can't reproduce any of these errors. I would suspect flakey hardware. I
just had an old Mac II that has been running without poweroff or failure for
almost two years -- and it started getty flakey. I finally took the cover
off and "stroked" the SIMMs and wiggled all the connectors and reseated the
PMMU. Now it behaves again. If the bug is repeatable, check your Ethernet
card to see if it has all the revs on it.
