It turns out there were two different problems, neither one caused by the driver. 1. I had some ARP poisoning going on on my LAN, and that's why the two em interfaces in the Dell box appeared to be behaving so strangely. I fixed that, and the box is working just fine now with the driver from -current (both with and without MSI). The evidence was right there before my eyes, but it sure took me a long time to recognize it. 2. On the Tyan 2721 box, it was MSI that was causing the problem. It appears that MSI simply doesn't work on that motherboard. Once I disabled it, the driver started working fine. I had tried disabling MSI on the Dell much earlier, but I guess I never tried it on the Tyan. Maybe if I'm lucky, I'll find a BIOS upgrade that will fix it. I apologize for wasting everybody's time as well as for taking a year or so off Jack's life through adrenaline poisoning. John
