I have no log messages in /var/log/apparmor/ . Folder is empty
/var/log/apparmor/ is only used for debugging mode of aa-logprof and other aa-* tools, so it's normal that it's empty.
As I said, I can provide more information about this, I just don't know where to start.
The full dmesg output ("dmesg > /tmp/dmesg.txt") when the system is slow is probably a good start. -- You are receiving this mail because: You are on the CC list for the bug.
