Whatever tool created the EFI system partition in the GPT table did it wrong. That the well-known UUIDs are translated to a string is a gnuefi lib stupidity. You would need to change the GPT entry to have a random object UUID, then all should work on gummiboot + systemd side. But be careful, if you have Windows installed, it might (I don't know) have trouble when the UUID is changed.
