Can you describe your setup and the boot order in more details? I guess there is some fundamental misunderstanding somewhere. Where does your kernel live and how is it loaded? What partition(s) have the bootme flag? I would never expect it to make any sense in the inner GPT of a raid set, but only the (outer) GPTs of the components (so firmware finds the bootloader). Martin
