Occasional failure to bring up inteface on boot

Hi,

I'm basically suffering exactly the same issue as described in this post from 2013: https://bbs.archlinux.org/viewtopic.php?id=170044

It's only started happening recently, but now about 50% of the time netctl fails to bring up my network interface on boot:

● netctl@enp3s0.service - A basic static ethernet connection
   Loaded: loaded (/etc/systemd/system/netctl@enp3s0.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Tue 2016-05-17 19:48:28 BST; 2min 7s ago
     Docs: man:netctl.profile(5)
  Process: 355 ExecStart=/usr/lib/network/network start %I (code=exited, status=1/FAILURE)

May 17 19:48:28 newton systemd[1]: netctl@enp3s0.service: Failed with result 'exit

Subsequent attempts to bring the network up fail for a different reason, presumably because the initial failure leaves the interface in an unexpected state:

I've been working around this issue by getting another address via dhcpcd (which works fine), although I'm now going to try the workaround suggested in the 2013 post.

Does anyone have any idea what might be going wrong here?

Thanks.
