[linux-lvm] scary message (incorrect header checksum)

[Marc Cousin]

        /dev/ram2: Skipping: Unrecognised LVM device type 1
        Opened /dev/hda2 RO
      /dev/hda2: size is 1012095 sectors

That's strange, as hda2 is a swap device ...
I've mkswapped it, didn't change a thing.
Si I zeroed it with dd, mkswapped it again, and the message is gone...
