Swap.
Which was installed last, Squeeze, or Jessie? You can expect this
message trying to boot the earlier installed installation after
having done the later install. Unless you take affirmative action
to deny it, an existing swap partition used by the earlier
installation will be reformatted by the later installation.
Reformatting creates a new UUID, thus making the UUID referring
to it in the earlier installation's fstab invalid. The earlier
needs to have its fstab edited to use the correct swap partition
UUID, or volume label, or device name, if swap is actually
desired or needed.
