For the apparmor trusty SRU, I reproduced the failure with the source for apparmor 2.8.95~2430-0ubuntu5.1 from trusty-updates with a hardware enablement kernel and confirmed that apparmor 2.8.95~2430-0ubuntu5.2 addresses the issue. I also verified that the rest of the apparmor regression tests passed.
