hmm looking at the boot message the policy
is already loaded,but errors out with atd.
(or after)
and you have bootparams= selinux=1 enforcing=0
and /etc/selinux/config in permissive?
if both are set into permissive(the policy should load), then the
next best thing todo is a bisect(just grab the latest refpolicy from
git), this way you can get a better idea of whats causing this.
if you need help with doing a bisect let me know.
