Rebuilding kernel with that patch.

What triggered the kernel problem was bug 1047. ceph-mds crashed on all nodes
with that assert. When the kernel detected that the main mds connection was
missing, it tried to reconnect and hung.
We do appreciate how much work you are doing to make Ceph production ready.
Thank you!
We really want to use Ceph in our product, because the design and experience
so far have shown a lot of potential.
