Comment 11 for bug 380138

All I done was...

1- Disable backup bios to disk in gigabyte bios if enabled

2- Disable HPA with HDAT2 (disk must be in sata mode not raid)

3- Back to raid mode and recreate raid

5- Particioning raid with other OS. (Lucid has a bug particioning raid disk, I used fedora 13 live usb)

6- Now install ubuntu (I had less problems installing karmic and upgrading before than doing a clean lucid install)

I wish that works for you too
