Description of problem:
On a Lenovo Carbon X1 laptop with an external display connected using a DisplayPort through a ThinkPad OneLink Plus Dock when the display goes into standby mode, sometimes the external display does not wake up.  When that happens a message like this is logged: 
[173383.338202] [drm:intel_mst_disable_dp [i915]] *ERROR* failed to update payload -22

Sometimes switching to the text Console with C-A-F2 and back would wake up the external display, some other times it would simply crash X.
