<pre>I am trying to get my daisy chain DP MST setup up and running but somehow the
second monitor is not turning on, I am using the Dell Monitor which has the
support for MST embedded within the monitor itself (not using the hub). Will
sync w/ Jim tomorrow on this.
Jim also suggested to manually unplugging the power when connected to the DP
MST hub and with that it reproduces a CPU pipe A FIFO underrun (it seems to be
a different problem than the null pointer because the kernel didn't crash, only
errored out).</pre>
