Thank you Tom for providing a log. The issue still persists and you keep
receiving a lot of short hotplug detection pulses.
<span class="quote">> As expected, flickering is still present. syslog attached.

During the patch review I received comments that I should move the idea of
tracking the config changes to its current location in patch
<a href="https://patchwork.freedesktop.org/patch/69394/">https://patchwork.freedesktop.org/patch/69394/</a>
If you have time, it would be interesting to know if you apply this patch
<a href="https://patchwork.freedesktop.org/patch/66697/">https://patchwork.freedesktop.org/patch/66697/</a>
on top of current -nightly and check if it still fixes the flickering.</pre>
