The problem the machine >is 50km away from here :-( You should be able to "ifconfig fxp0 down; ifconfig fxp0 up" to restore it. ...and yes, it is possible to work around the problem in software via a disgusting hack, but I haven't done that yet. For now, you might consider writing a script that pings another machine on the ethernet and if it doesn't get a response, ifconfig down/up the interface...perhaps trying once per minute or something. Sorry that this is a problem for you. It's not a bug in the driver, however, so I don't feel too bad. :-) -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
