Each time I’ve installed Ubuntu on my current desktop, the network adapters have failed to work ‘out of the box’. The culprit is the 680i chipset that my motherboard uses. There’s a simple fix, however: the forcedeth module needs to be loaded with some special sauce. A quick way to make it work is as follows:

sudo rmmod forcedeth
sudo modprobe forcedeth msi=0 msix=0

You should see the network adapter spring to life. Assuming that works, you can make the fix permanent by adding the following line to /etc/modprobe.d/forcedeth.conf:

options forcedeth msi=0 msix=0

and then running

sudo update-initramfs -u

and rebooting to save the changes.

Guess what! If you install Ubuntu 9.04 with /boot on an ext4 partition and you previously had grub installed into the MBR (and were using ext3), your system won’t boot! You need to boot the live cd and manually run grub-install.

# /dev/sdc2 has /boot on it, amongst other things
sudo mount /dev/sdc2 /mnt
sudo grub-install --root-directory=/mnt /dev/sdc2
