On Xenial, this test will time out as well, but with slightly different error message:

For the fanotify09 test with Bionic kernel, it's now failing with another new test case landed 2 days ago: bug 1804594

The timeout in X was caused by some other failures in previous tests.

If you run this test on X after a clean reboot, it will be:

So it's the second test that's failing, which was report in bug 1804594

Therefore I will invalid the xenial related task here.
