As of the last few days, I also have an apparmor issue:
Feb 29 15:35:33 DOUG-64 kernel: [25130.612529] audit: type=1400 audit(145678893 3.480:15) : apparmor="DENIED" operation="open" profile= "/usr/sbin/ named" name="/ proc/sys/ net/ipv4/ ip_local_ port_range" pid=4932 comm="named" requested_mask="r" denied_mask="r" fsuid=109 ouid=0
but if I set that apparmor profile to "complain" mode, then my kernel will crash during the shutdown phase of a re-boot.
Otherwise, and as far as I know the DNS is actually working properly.
