ifplugd/e1000 oops

I'm using ifplugd to monitor the link beat and automatically bring up
or down the network interfaces on my laptop.

When I unplugged my cable today, I got an oops. When I plugged it back
in, nothing happened. (Normally it should beep and bring the interface
back up.) When I removed and inserted the e1000 module, I got a freeze.



e1000: eth0 NIC Link is Down
