Bug Description

Testing failed on xenial/linux-hwe 4.15.0-45.48~16.04.1:
    arm64: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-xenial/xenial/arm64/l/linux-hwe/20190201_153130_e7a9e@/log.gz

xenial/linux-hwe ADT tests have been timing out on almost every run on arm64.

This is not a regression on ADT, the linux-hwe results had been ignored until recently.

From a quick look at the logs, it seems that a lot more time than it should.

on arm64:

13:46:55 INFO | START ubuntu_qrt_apparmor.test-apparmor.py ubuntu_qrt_apparmor.test-apparmor.py timestamp=1549028815 timeout=10800 localtime=Feb 01 13:46:55

So that one took almost 1h40 min to complete, being most of the time spent on this part:

Whereas, on amd64[1] it took only ~17 min:

12:38:52 INFO | START ubuntu_qrt_apparmor.test-apparmor.py ubuntu_qrt_apparmor.test-apparmor.py timestamp=1549024732 timeout=10800 localtime=Feb 01 12:38:52

This testcase could be not the only culprit, but it would be a start for investigation.
