It's as if there is a huge network delay (there is no traffic on the network). When logged into the machine directly via a console, I can not detect any of these "stalls". I have tried a different 3com 3c980c card and the second card had the same problem. Here are relevant sections of my dmesg's and ifconfig: Copyright (c) 1992-2001 The FreeBSD Project.
