no connection after boot with match statement

[Thomas]

Hi,

when I use netplan with a match statement, my network is not fired up after reboot. I have to manually run "netplan apply" and than the interfaces are ready.
Without the interface get not renamed and also not applied to the bridge.
And systemd-networkd.service stucks at boot and is waiting for the network to get ready, but fails at least...

root@host:~# cat /etc/netplan/01-netcfg.yaml
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
  version: 2
  renderer: networkd

  ethernets:
    enp1s0:
      match:
        macaddress: 00:22:4d:b1:b6:ac
      set-name: lan1
      wakeonlan: true
      dhcp4: no
      dhcp6: no
    enp2s0:
      match:
        macaddress: 00:22:4d:b1:b6:a8
      set-name: lan2
      dhcp4: no
      dhcp6: no
      optional: true
    ovpn0:
      dhcp4: no
      dhcp6: no
      optional: true

  bridges:
    br0:
      interfaces: [enp1s0]
      dhcp4: true
      dhcp6: true
      parameters:
        stp: false
        forward-delay: 5

The funny thing is, when I not use netplan to rename the interfaces (so I commend out match, macaddress and set-name) the network lifes after a reboot.

Any way I can debug this problem?
