Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.13 kernel[0].

If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".


Thanks in advance.

  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.

  Ubuntu release: 14.04 Trusty Tahr (development branch)
