I tried somes NIC (requeired e100, e1000 and tg3), I don't faces this issue. So, it may be an issue of NIC / driver. I don't know it's related or not as I don't have Davicom NIC, it seems that 2.6.15 kernel has an issue with Davicom NIC. Regarding udev, kernel gets the tulip driver. It seems to cause some troubles. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=326723 Let me suggest you try the way written at the above-mentioned page.
