It looks like you have two partitions labelled /boot
I think you have probably come across this bug: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=156949
util-linux-2.12a-24.2, which has just been mentioned on fedora-announce-list, is supposed to fix this. You'll still need to move the files from the /boot directory in your root partition to the "real" /boot partition though.
