Arch Linux - br0 is down, or has no allocated address

I'm running archlinux-on-b3 with the latest modifications (thanks a lot, sakaki, for maintaining it!). After recent updates, I noticed my IRC bot started dropping off. It turned out that the old IP is not retained, when DHCP lease expires.

This is seen in journal:

Code: Select all

touko 05 15:03:41 archb3 systemd[1]: Starting A lightweight DHCP and caching DNS server...
touko 05 15:03:41 archb3 dnsmasq[2113]: dnsmasq: syntax check OK.
touko 05 15:04:11 archb3 wait-for-br0.sh[2114]: br0 is down, or has no allocated address
touko 05 15:04:11 archb3 systemd[1]: dnsmasq.service: Control process exited, code=exited, status=1/FAILURE

touko 05 15:04:11 archb3 systemd[1]: Failed to start A lightweight DHCP and caching DNS server.
I have read the topic about the wait-for-br0.sh script, but I am out of ideas on what might be the cause. My dnsmasq service is the one in the topic.
I am not using Shorewall (as advised by the readme of archlinux-on-b3).
I am not using wifi.
