This problem has surfaced again with recent MAAS Ubuntu images. One report in bug 1701297. I have information about at least two other end users hit by the problem.
Adding a workaround by setting apparmor=0 kernel parameter in MAAS 2.2 will not help users that are running previous versions.
@jdstrand Would you care to reference the other bugs you created from your investigation?
