Yes, I guess that is an unrelated error. However, my patch also wasn't correct because it is not allowed to have an empty list of objects. There is an updated patch below, I could add that straight to the branch that caused the problem if it looks ok to you.

This means we enable code that is not going to be used without a machine descriptor referencing it, but only if the kernel is configured specifically for this case.
