Comment 13 for bug 1626894

Sorry for the late respond, I didn't have access to the hardware during the weekend.

I've just tested both kernels and can confirm, that the second one works correctly:
----------------->%-----------------
root@Ubuntu-1604-xenial-64-minimal ~ # uname -a
Linux Ubuntu-1604-xenial-64-minimal 4.4.0-40-generic #60~lp1626894Commit30d6592Reverted SMP Fri Sep 23 17:06:33 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Let me know, if you need any additional testing.
