<pre>I just noticed that although 60Hz now works fine, 30Hz stopped working. When
setting the mode to 3840x2160@30Hz the screen stays blank and dmesg says the
following:
[drm:intel_cpu_fifo_underrun_irq_handler] *ERROR* CPU pipe B FIFO underrun
However, from my side I consider that to be a minor issue.</pre>
