After upgrading kernel to 4.0.2, when an unprivileged container is
started, the kernel hangs up. (I use lxc 1.0.7 and today's master
branch) 4.0 and 4.0.1 kernel is no problem.

I paste trace log at:
  https://gist.github.com/tenforward/01670c4ee77f0bf4d44d

I reverted some commits from 4.0.2, it resolved.
  https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-4.0.y&id=20e62ee6fa3da23a792ca31d4b68069060317260
  https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-4.0.y&id=c076cbf218f3cb83dffe6982587d2b9751318962

Do someone encounter the same problem? Is it a kernel bug?

Thanks,
