There were several fxp(4)changes made since FreeBSD 8.3-RELEASE but I don't see any fxp(4) commits that may result in DHCP issue above. I recall there was a dhclient(8) change that makes dhclient track link state. Could you rebuild dhclient(8) and try again without that change(i.e. locally back out r247336)? > > I've attached a verbose dmesg from 8.4-RC3 and a standard dmesg from > 8.3-Release p8, and can provide whatever else you need. > > This is not a critical issue for me.
