Not sure why suddenly a very slow boot when I start Ubuntu. Now it is about 3 mins to boot fully. The dmesg:
[ 6.446195] audit: type=1400 audit(1481821642.925:11): apparmor="STATUS" operation="profile_load" profile="unconfined" name="/usr/sbin/clamd" pid=794 comm="apparmor_parser"
Then the next line:
[ 94.175197] cgroup: new mount options do not match the existing superblock, will be ignored
So obviously here is the problem. Not sure how to fix. help?
