This is a brand new install and the livecd had issues with the adapters, but it worked well enough. My compiled kernel cannot find the devices even when using genkernel. When I boot the livecd, lspci -v gives me this about them:

My kernel config has:
Quote:
livecd linux # cat .config | grep FORCEDETH
CONFIG_FORCEDETH=y


edit: oops - hit submit instead of preview.

Thank you in advance for any help

edit: More info

Loading the forcedeth module with the msi=0 and msix=0 stwitches has no joy. I noticed that both the driver and udev are changing the name of the interfaces. Both interfaces are being given the same name and, no, the odd named interface doesn't work.

either
read news (eselect news read all) and create: If /etc/udev/rules.d/80-net-name-slot.rules is an empty file or a
symlink to /dev/null, the new names will be disabled and the kernel will
do all the interface naming, and the resulting names may vary by kernel
configuration, hardware configuration and kernel version. After which you can use etho and eth1
or
run
Code:
 ifconfig -a
which should give the device names that udev has assigned
create symlinks, add to run level, start, check on them
cd /etc/init.d
ln -s net.lo net.device name that udev has assigned
ln -s net.lo net.other device name that udev has assigned
rc-update add net.device name that udev has assigned default
rc-update add net.device other name that udev has assigned default
/etc/init.d/net.device name that udev has assigned restart
/etc/init.d/net.other device name that udev has assigned restart
ifconfig

Eliminating the msi=0 and msix=0 switches resulted in two odd named interfaces that, when substituted for eth0 and eth1, work fine. Thank you.
