I just tested 2.6.32.23 and I cannot ping local ipv6 addresses after
the loopback interface is brought administratively down and back up.
So it looks like we have some old bugs getting in the way an recent
changes that are reasonable. I don't expect that it is by design
that bouncing the loopback interface breaks the ipv6 stack.
