Hi!

That=E2=80=99s on Git master, right?

Could you post tests/syscalls.log?

This test is known to be problematic with recent kernels, as written
above it:

--8<---------------cut here---------------start------------->8---
;; XXX: Skip this test when running Linux > 4.7.5 to work around
;; <https://bugzilla.kernel.org/show_bug.cgi?id=3D183461>.
(when (or (not perform-container-tests?)
          (version>? (utsname:release (uname)) "4.7.5"))
  (test-skip 1))
--8<---------------cut here---------------end--------------->8---

AFAIK this particular problem was introduced around 4.7.5, as discussed
in the bug report above, but maybe Ubuntu=E2=80=99s 4.4 has it too?

Thanks for your report!
