For some reason the network modules aren't functioning correctly in 2.6.15 or higher. I have tried to upgrade the kernel on both an nforce 4 board which uses the 'forcedeth' module and an nforce 3 board which can use either 'sk98lin' or 'skge'. I can load and unload the modules, but eth0 never shows up...all I get is loopback. 2.6.14-r6 and below have all worked just fine, haven't tried 2.6.14-r7. I have also tried starting from a new .config file, same issue. all etc-updates have been performed. Let me know if you need more info.
Please concentrate on just one system first (preferably the forcedeth one). Post the following: emerge --info ifconfig -a lsmod Attach the following: "lspci -v" output kernel .config "dmesg" dump
after running your tests, I got networking running on both of them. I had not noticed that the kernel decided to assign the network modules to eth 1 instead of eht0. I don't understand why i am now dealing with i eth1 instead, but it works so i don't care too much.
