As soon as I change the switch to 100BT / half duplex, everything is fine with no errors for last 30 minutes. So, is the de driver lying to me when it sayd Full Duplex? Collisions should be impossible in full duplex mode and, if I had a mismatch with the switch, I should see errors after the change. /\/\ \/\/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
