Bug description:
To start with, let me confirm that I do NOT have any message in my
kernel log complaining about the kernel not being able to set the
default IPv6 route, so that's a different bug from the what you're
probably thinking about ;)
This one happens every few minutes or every few hours, as far as I can
tell, only on wireless networks (for a yet unknown reason) and only on
dual-stack networks.
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
