network-manager in ubuntu precise use incorrect /64 prefix from dhcpv6 client which cause that internet connection not working on some ipv6 networks. this problem was fixed in upstream network-manager version 0.9.6 which is already available in ubuntu quantal and newer - but not in ubuntu precise. because this is critical problem (non working network/internet) new version of network manager (e.g 0.9.6) or at least patch which fixing this problem should be included in ubuntu precise which is LTS.
