I have installed ubuntu (7.10 i think) on this machine before, and didnt have any problems using dmraid then. Suddenly the installed ubuntu stopped working, and when I tired to reinstall, then dmraid reported "No RAID disks".
A copy of vista is running just fine on the raid.
I have followed the instructions on https://help.ubuntu.com/community/FakeRaidDebug and i will post the results of the tests suggested there.
hope somebody are able to help me out, I use the onboard fakeraid (ICH9R) on GA-P35-DS3R.
results:
