>Description:
When running a telnet session from or into the machine, it looks like there is a very noticable delay between typing CR and other characters
and when these characters are displayed at the telnet session. 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:
