Some time ago I have sent here (and to one of IPv6 maintainers) a patch
fixing 2.2.x-kernel auto-configuration bug. It seems it was not included
in 2.2.17 kernel.
The problem I was fixing was "disapearing" "all-nodes" multicast
address. After the interface went down and up it lost the ff02::1
multicast address and it received no RA. After removing and loading the
module it would come back and auto-configuration worked again.
I hope this helps.
