Confirmed. There is a kernel locking bug that can cause the machine to freeze
on profile replacement/removal, if all the loaded profiles names are greater
than a page in size and the replacement/removal is done after looking at

cat /sys/kernel/security/appamor/profiles

or

rcapparmor status
rcapparmor restart
rcapparmor stop

The initial profile load should not cause problems, and profile
replacement/removal is safe from the parser, as long as the above commands have
not been done.
