What I see is similar, but not identical to Gábor's description:

Notice that in my case, it says "Xorg Tainted", where Gábor sees "Xorg Not
Tainted". Not sure if it's the same bug, but it sounds like it might be. I'm on
Ubuntu 14.04 ("4.4.0-64-generic #85~14.04.1-Ubuntu SMP Mon Feb 20 12:10:54 UTC
2017 x86_64 x86_64 x86_64 GNU/Linux"), on a Latitude E5570. Fresh install a few
days ago.
