The resumeDevice and kernel `resume` parameter were being used wrong. Only `boot.resumeDevice` is necessary, and it should point at the _block device_ that holds the swapfile. If you are running on encrypted volumes, this means you will need to use the name of the *decrypted block device* on which the swapfile sits.
