Ah sorry.

In my case the router lifetime is much shorter ( a few minutes ) and
expired by the time I get home, which is why I was only faced with the
"using bad source address" issue.

In anycase, following Dan's reponse, I just flush all ipv6 on suspend
now ... (NetworkManager was a bit heavy-weight to just sort that
particular issue ...)


Cheers,
