Thank you Joshua and Simon for looking into this. My server wouldn't
start because of a corrupt data directory, it came back up when I fixed
it.
I was seeing a lot of these apparmor messages in the system log and they
were being printed very frequently, so I thought they might be related.

Public bug reported:
I noticed this because mysql failed to start after I rebooted my
machine. I initially thought this was because of a change in mysql:
[ 1323.162491] audit: type=1400 audit(1488154060.141:39): apparmor="DENIED"
operation="open" profile="/usr/sbin/mysqld" name="/sys/devices/sys
