Hello,
this morning I checked out Linus tip and compiled it after booting my

I also have IPv6 with link-local and global addresses configured.

Kernel Config is at: http://pbot.rmdir.de/VTAnhVv8ECP7a7SPaxMsFA

I'm available for testing fixes or providing ssh access to the system if you
want to do further tests. I have the same config running on 3.13.0 on the same
machine without any problems whatsoever. If I should bisect it, let me know.

Cheers,
        Thomas
