In my case, I have a Raspberry Pi B+ working as a wireless access point, so I have eth0 bridged to wlan0.
The symptom is that br0 is not coming up and even if I manually bring it up and restart systemd-networkd, then DHCP doesn't get an IP address.
Manually setting the IP address and default gateway gives me a "normal" system again - so this is my only symptom (but it does mean dusting off a monitor and keyboard to resolve the problem )
$this->bbcode_second_pass_code('', 'uname -a') shows that I'm running 4.19 kernel, so I'm not running an old kernel as per the other post, so this is a different situation.
If I downgrade systemd-libs and systemd to 244.3-1 (that's what is in my cache), then everything works fine.
I'm not sure where to go from here really... any pointers?
