That is to be expected if the display port sink replies with repeated
aux defer messages. Error for the retry limit first, then error for the
modeset failing due to this. Don't worry about it.

(The modeset failure message comes from the post-modeset state checker.
We could handle this more gracefully, but there are scenarios where the
failures we detect during modeset do not result in a non-working
display... while bailing out early would definitely result in a non-
working display.)

  Lenovo T440s freezes when connected to docking station

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  This bug report looks to be for the same issue:
  https://bugs.freedesktop.org/show_bug.cgi?id=71267

  I came across the above bug report here:
  https://bbs.archlinux.org/viewtopic.php?pid=1374408

  I'm running with a Thinkpad T440s and ultra dock with hdmi<->hdmi.  In
  my case if I dock when hdmi is connected to the dock, the mouse and
  keyboard freeze once connected.  When I undock they unfreeze.  If I
  dock when hdmi is not connected to the dock, the mouse and keyboard
  don't freeze.
