Thanks for motivating me to investigate this further. I have to apologize. It is not a kernel issue. It has turned out that systemd, starting with version 229, has placed a "Not invented here" stamp on route advertisement processing in the kernel and has implemented its own userspace code to handle router advertisements. And, of course, they did it wrong. Setting IPv6AcceptRouterAdvertisements=0 in eth0.network seems to disable enough code that this issue does not show any more. Sorry for the rumble, I debugged the wrong piece of software. Bugs in Debian are filed, #815582, #815586. I don't file bugs with systemd upstream any more since I got silenced on systemd-devel for losing my temper.
