[systemd-devel] timesyncd log messages galore

[Ede Wolf]

Thanks. Indeed, stopping radvd made these messages stop appearing.
Now I am no IPv6 guru, but having routeradvertisments is not too 
uncommon, to the best of my knowledge.

So the punchline is, that timesynd is not really usable with ipv6 
networks? Am I getting that correct?

After all, an ra does not really change any network configuration and 
since the issue you've related to is rather old, this does not seem to 
be considered as a bug?

Especially, since the ntp in this case is ipv4 only and completely 
unrelated to ipv6. If it can reach its ntp, why those messages?
