Managed to get rid of the infinite loop complaining about a bad superblock on /dev/hda, now it just loops happilly saying the md device already has it's disks.
I suppose this means it's atleast assembling the raid. I found an upstream bugreport about a simular issue that's apperently already solved in debian, this is the link: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=396582 -- Feisty Beta Installs ok, doesn't boot https://launchpad.net/bugs/95280 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
