I seem to have hit this as well, in a Fedora 24 Docker build on Travis CI (note that I can't reproduce the issue using the exact same container and build steps when running them on Docker for Mac 1.12.1...). See: https://travis-ci.org/geerlingguy/ansible-role-redis/jobs/160756445#L298

for reference, running privileged works, but not --cap-add=SYS_ADMIN

    run_opts: "--privileged --volume=/sys/fs/cgroup:/sys/fs/cgroup:ro"

as seen here moby/moby#7459
seems for cap-add need an unreleased docker.
