Re: [gentoo-user] no net modules will load

[Maurice E Johnson]

It would seem that you failed to configure the necessary modules for
loading any of the modules you list.
Also, as of kernel 2.6.13, devfs is no longer in the kernel and you must
use udev. without it you will never get your devices to be recognised.

I do hope you kept your old kernel around so that you can boot to it.
