I have a few EN-15000 and SN-18000 motherboards attached to different = types of switches. With the SN-18000 on FreeBSD 7.0R-p1 to make the vge NIC function even after rebooting I need to unplug the NIC's. Doesn't matter what switch, or even using a crossover cable, the card needs to = reinitialise itself. This may be similar the problem that you're experiencing. And = as Pyon YongHyeon mentions there is a lot of variety with rl and re cards, = I also use re in my ITX motherboards, without experiencing your issues. Also, after rebooting your machines try performing tcpdump -vv on the interface that isn't working while (ie before & after) you try the unplug/plug sequence. (vge's since 6.1R experience a lot of incorrect checksums.) I'm suggesting these steps as they might also assist others with clues to assist diagnoses with your re's) Regards, Dewayne.
