I am seeing the same behavior with kernel 2.4.0/unstable. I've not
found a way around it yet. I've got one unstable box working fine with
IPv6, but 2 others simply won't do it.
Another odd symptom is that the machines that return invalid argument
when trying to ping the link local address can't react properly to
router advertisements. The box on which IPv6 does work is able to
auto-configure itself with no problems at all. The other 2 never get
their global scope addresses. I know they're seeing the router
advertisements because I've watched the solicitation/advertisement
conversation through tcpdump...
One of these non-functioning systems has been set up specifically to try
and debug this problem, so if anybody is willing to give me some
pointers we can try just about anything with it.
