Comment 29 for bug 1871148

With snapd 2.55.3+22.04ubuntu1 and apparmor 3.0.4-2ubuntu2 from Ubuntu 22.04 (Jammy Jellyfish) :

- On a machine with a powerful i7-7700 HQ processor, the issue did NOT appear yet.

- On a machine with the slower AMD FX-8370E processor, the issue occurs systematically after each reboot.

   $ sudo systemd-analyze critical-chain apparmor.service snapd.service

   apparmor.service +396ms
   └─local-fs.target @3.660s

   snapd.service +529ms
