I saw a problem like this with the old driver some time ago, where
the automatic media detection stuff on one of those cards would
get confused if the hub the card was plugged into went away for a
few seconds. The card would switch to the AUI or coax port and then
get stuck that was.  You had to up and down the interface to fix
it. This problem is seemingly due to the disign of the media
detection on the cards, so similar trouble may still exist with
some cards?

You could try hard wiring the media type and see if that makes a
difference.
