On generic B-5.0 kernel, this test just failed with launching session
daemon:

Error: Problem occurred while launching session daemon

** Description changed:
Test will crash and hang, until timeout on jenkins.
+
+ This test passed with B-4.15 AWS, and D-5.0 AWS, just not B-5.0 AWS
There is no report and no obvious failure on the jenkins output (just
marked as build aborted), this can only be found by tailing the syslog
when you run the test.

Bug description:
Test will crash and hang, until timeout on jenkins.
This test passed with B-4.15 AWS, and D-5.0 AWS, just not B-5.0 AWS
There is no report and no obvious failure on the jenkins output (just
marked as build aborted), this can only be found by tailing the syslog
when you run the test.
Test output:
