autopkgtest fails on ppc64el

[Michael Hudson-Doyle]

Ever since version 2.6.5-2ubuntu1, the autopkgtest for udisks2 has been very flaky (failing ~80% of the time) on ppc64el: http://autopkgtest.ubuntu.com/packages/u/udisks2/artful/ppc64el

We attempted to debug a little and managed to reproduce in a VM but we got confused trying to debug:

[00:09:15] <cpaelzer> Summary:
[00:09:17] <cpaelzer> - directly calling asubtest fails (call_lock_sync), you need to run all Luks tests as they depend on each other
[00:09:18] <cpaelzer> $ sudo src/tests/integration-test Luks
[00:09:19] <cpaelzer> There it mostly fails at one of (always a different) test
[00:09:21] <cpaelzer> - Once the bug was triggered by any of the tests in Luks it can be ran into with a subtest alone like
[00:09:23] <cpaelzer> $ sudo src/tests/integration-test Luks.test_ascii_keyfile_newline
[00:09:24] <cpaelzer> - at some point after the issue further tests block at being unable to remove scsi_debug (needs reboot)
[00:09:26] <cpaelzer> - nothing obvious in dmesg, or journal neither on usidk nor scsi_debug
[00:09:27] <cpaelzer> - I've run a small dbus checker and it lists org.freedesktop.UDisks2 still as active
[00:09:28] <cpaelzer> With udisk giving neither a crash nor any sort of message and the test only reporting a lost connection on the Dbus service I leave it to you to continue tmrw

The autopkgtests look pretty reliable since mid-December

http://autopkgtest.ubuntu.com/packages/u/udisks2/bionic/ppc64el

There is still a hint for udisks2/2.6.5-2ubuntu2/ppc64el
Maybe that's useful a bit longer for artful SRUs?
