No differences in dmesg. The interface reports it is up, however doesn't respond to ping. Network manager reports it down. I enabled and disabled the networking. That didn't bring it back.

I will have to run through bisect again. There are other ipv6 related patches in this release. I will let you know what I can find. I don't think it is driver/hw related. thanks, -- Shuah
