I think this may be a hardware fault: I have now identified what
appears to be the physical situation under which this bug manifests
itself: it reliably occurs when I attempt to connect to an ethernet
without my power supply connected (i.e., running from the battery),
and never seems to occur when I am on main power. So that is why I
think this is a hardware fault - I guess the bug should then be
closed?
