However, I see similar problems when running the 4.4 kernel, so this might not be related to the "shell hanging" problem.I just installed linux-image-4.6.0-rc3-amd64 from experimental. With this kernel, I can run `docker start`, and I get a bash root prompt using `docker exec -it <container> bash`. However, the shell then hangs: I can edit the line, but even w/o entering anything and just hitting <enter> the shell locks up./var/log/messages shows:
