Is it still working?
Did someone bump the ethernet cord?
How repeatable is it?

Same ethernet card?
Might be different behavior depending on what card you have. I'm not sure of how they work if the ethernet card was actually transmitting something and the cable is disconnected...

Is certainly not the same network interface ...

Well, same brand/model of ethernet card. Perhaps the drivers deal things differently. I would imagine the e1000 driver is pretty well written with card well designed, not sure of some other cards.
