The interface is xl0 (3Com 3c905C-TX Fast Etherlink XL), and it worked 
in this machine fine for as long as i remember. This seems to have 
happened since a recent cvsup and buildworld from ~6-BETA to 7-CURRENT. 
I rebooted three times, and the problem occured rougly a minute after 
bootup. On the fourth time however, it seems to be ok so far.
