Comment 18 for bug 106931

I should add, that pata_821x will continue to load at boot time and prevent it821x working, so you'll need to remove that module more permanently.

Running "update-initramfs -u" after removing pata_it821x and installing it821x will update the initrd boot image for the current kernel, removing the pata_it821x module from those being loaded at boot time and adding it821x.

When I did this, the hda, hdb etc mappings changed because the it821x driver loaded first (the raid array became hda and what had been hda became hdi). Luckily, the new UUIDs mean this doesn't actually break anything.
