I'm not convinced yet, that your system screwed up partition and/or device ordering. First you should try to find out which devices are recognized both in Fedora and Ubuntu and compare these. Try to run 'lsblk', 'dmsetup ls' and 'dmsetup deps' on both systems and compare or post the result here. Which Ubuntu version do you run? Do you use an installed Ubuntu or rather a live image? It would help if you could provide some more information regarding your system.
