The assumption based on the redhat bug report is that rdnss data is sometimes expiring before the RA, triggering the bug. I'll workaround this at home by bumpding the rdnss expiry to be 10 times longer than the RA and see if the bug still occurs throughout my network (30 or so clients in total, most of them on 12.04).

I reproduced it on a variety of equipment (3 laptops, 2 with 2 different intel wireless chips, one with atheros) and on 4 different brands of access points. Only thing in common, the network configuration is almost identical. That's a standard dual-stack setup with IPv4 provided over DHCP and IPv6 through radvd (SLAAC) with RDNSS set. I'm attaching a debug log. Look for "ip-config-unavailable" to spot the few occurrences of the bug in it. This most likely is the same bug as described in: https://bugzilla.redhat.com/show_bug.cgi?id=753482 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/993571/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
