Title:
  uc20 image on pi often cannot get ip addr via eth0 on first boot of
  run mode

Status in subiquity:
  Incomplete

Bug description:
  Using the arm64 raspberry pi image from http://cdimage.ubuntu.com
  /ubuntu-core/20/beta/20200514.2/, I often cannot get console-conf to
  connect on the run mode boot. Console-conf shows there is no dhcp info
  on eth0 and it is disabled. If I try to enable ipv4 on eth0 interface
  with console-conf it just spins for a few minutes before I give up and
  reboot the pi again.

  After rebooting, it is then able to get an ip address. This seems to
  be 100% reproducible for me, the same Pi with classic focal does not
  have this problem.

  This also affects recover mode, in that basically every "first boot"
  of recover mode fails to get an IP address and so I have to reboot it,
  then it gets an IP address and I can login via SSH.

  Note that this same exact Raspberry Pi 4 with the same network cable
  and same network and power supply, even SD card doesn't have this
  problem with UC18 (though obviously the SD card is re-flashed).
