I'm using >4.0-RC2 with the following chipset: I get the same messages on my dc1 on my "lan" - just a win98 box connected to the freebsd box. dc0 is connected to the internet with a DSL modem and I've yet to see this on dc0. I swapped interfaces also, but it only seems to happen on the local network. My local network also goes down, it could be five minutes or two hours and I have to do an ifconfig dc1 down/up to make it right again. As a workaround, I found that running tcpdump on the dc1 interface keeps things alive, so far indefinitely. -Bryan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
