It seems to have no adverse effect, that I have noticed anyway. Reproduces
reliably.

[drm:intel_dp_start_link_train] *ERROR* failed to enable link training
[drm:intel_dp_complete_link_train] *ERROR* failed to start channel equalization
[drm:ivybridge_set_fifo_underrun_reporting] *ERROR* uncleared fifo underrun on
pipe A
[drm:ivb_err_int_handler] *ERROR* Pipe A FIFO underrun

This is with an Intel NUC (Haswell) on Ubuntu.
