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.

Unexplained network outages

[Bryan Liesner]

I have a win98 box connected to a 4.0-current box via an ethernet
connection.  The connection will go dead after about 20 minutes. I'm
unable to ping the win98 box and cannot ping the FreeBSD box from the
win98 box.  No error/console messages.  I can bring it back to life by
doing an ifconfig dc1 down/up, then pinging the win98 box.  Has anyone
experienced this behavior? 

The strange thing is that the network never goes down if I run tcpdump
in promiscuous mode on the interface - it's a workaround, but I don't
like it.

Any ideas would be greatly appreciated.

Here's the output from ifconfig and dmesg:
