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
