Comment 4 for bug 220493

Okay by going to the site mentioned by Stefan I was able to test out his fix and get it working. This is what I did;

1. Added the sources listed on https://launchpad.net/~stefan-bader-canonical/+archive to apt
2. Did a apt-get upgrade which upgraded the linux-ubuntu-modules
3. Rebooted once that was complete
4. ctrl-alt f1 to see if any error messages to appear, and the following did ""ERROR: device-mapper target type "raid45" not in kernel"" however it did load my raid array and mount it as my /home and is working.

* Note; I did modify my startup in the previous distro to put a delay in the startup due to lag issues with my drives, however not sure if this carried over for the upgrade to hardy heron. SO Ill have to find the file and check this later to see if its still needed.
