Done some more digging into this and I have a feeling it's to do with IPv6. The interface gets several IPv6 addresses assigned (not sure if this is an issue). If I turn off IPv6 support, for this interface, in the Gnome Settings window, the interface recovers and stays up.

Upon boot, the wired connection comes up fine but, after a seemingly random time, the interface fails. If I watch the NetworkManager journal and try and switch the interface off and then back on in Gnome Control Panel, the interface keeps timing out: Sep 01 10:40:58 mia NetworkManager[3198]: <info>
