You could run networkd manually as
# SYSTEMD_LOG_LEVEL=debug /usr/lib/systemd/systemd-networkd
but this will also show endless DISCOVER attempts. In my case, I controlled the
DHCP server, and according to its logs the lease is actually assigned but the
client never receives it. So, I suspect a bug either in kernel or systemd
because packets get lost in the bridge (or bond in my case). I suspect the
former because restarting networkd didn't help (i.e. the DHCP lease never got
received).

Netctl is better in this situation because it allows ordering of different
profiles w.r.t. each other because they are just systemd services (in networkd
language this would be ordering of different .net* units if such existed). So
you can first set up vlans, then bridge and do the DHCP stuff.
There is an additional problem with networkd: you never know how to order
against it. Sure there are network* targets (and ideally things _should_ work)
but they are useless in this context because they can be reached before
(virtual) devices are actually initialized. OTOH, when a netctl script
successfully returns, you know that things are properly set up.
Hopefully this thread attracts relevant attention because I don't know how to
debug this...
