The UUID abstraction happened during the transition from dapper-->edgy. I suspect you have edited /etc/fstab by hand. Now that Feisty uses lib_pata, you must use UUID or /dev/sdX names.
** Changed in: linux-source-2.6.20 (Ubuntu) Importance: Undecided => Low -- Feisty will not mount partitions without UUID in fstab https://launchpad.net/bugs/94339 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
