I can not reproduce it on my machines, but judging by "Ip6OutNoRoutes"
there is no route to the local_addr (::1).

Looking at the kernel code, I see that kernel does add link-local
address automatically in init_loopback(), but that is called from
ipv6 notifier block. So, in turn the userspace that brought up
the loopback interface may see rtnetlink ACK earlier than
addrconf_notify() does it's job (at least, on a slow VM such as netdev).
Probably, for ipv4 it's the same, judging by inetdev_event().

The fix is quite simple: set the link-local route straight after
bringing the loopback interface. That will make it synchronous.
