Yeah, same thing here. This is the first machine I've owned in years that actually required that. Basically it failed to boot as RAID so I blew the install away, did it as non-RAID and had the same problem. Guess that might be it and tried it non-RAID and it worked. I haven't gone back to a RAID install yet due to issues in my other thread. Until I solve those I think I'll stick with the current install.
