I got the same set of warnings, and had the same issue (i.e. a partition
table residing in the mbr of my swap). I just recreated my swap and all
was fine:

    swapoff -a
    mkswap -f /dev/sda2 # WARNING: Make sure the device name is correct.
			# -f means "force". Wrong name = lost data.

You have to use the "-f" flag, otherwise your old boot sector won't be
erased. On successful completion, you should get no warning message, and
mkswap should have printed a UUID. Edit your /etc/fstab and replace the
UUID of the old swap partition with the new one. Then run

    swapon -a

and you're good to go.
