This did not happen on the same machine using FreeBSD 3.3 . I am using the dc0 driver now for the NIC and under FreeBSD 3.3 I used the mx0 driver. I receive errors on the terminal indicating tx underruns - I'm lucky to get 20kbs throughput >How-To-Repeat: transfer a file over 100k through the NIC >Fix: I wish I knew how to switch back to the mx0 driver! >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
