I don't see this beavior on the aarch64 systems I have available.

NetworkManager is the default, and we want to keep things as close to
the x86_64 version as possible for basic use and operation. It would
probably be helpful to track down why it might be changing or unavailable.

Which kernel are you using?
What names are you getting for the interfaces?
Is there anything different about the old interface config vs the new?
(Is the mac address different, etc)
