IPv6 dead in -bk11

IPv6 works 100% for my workstations in 2.6.10-rc2-bk2, but fails in 2.6.10-rc2-bk11:


        [jgarzik@sata g]$ ping6 www.kame.net
        connect: Network is unreachable

100% reproducible on multiple machines (x86, x86-64). Fedora Core 2 userland. The only difference is the kernel, no configuration differences account for this. dmesg and config are attached, but IMO are unlikely to be helpful.

Did someone break the IPv6 routing code or something, perhaps?

I'll narrow down which -bk snapshot broke IPv6 later on today...

        Jeff
