We upgraded our machines from CR repository a couple of days ago, but we didn’t reboot them.
Except for the issue with Samba authentication, for now we didn’t hit any more bug.
Edit
@dnutan I see this on you log:
Sep 13 22:22:49 server.domain.tld kernel: XFS (dm-0): unknown mount option [acl].
Could you try to remove the acl option?
