Hi,

today i tested kernel drm-intel-nightly
(5f13745078ab86d9833a181980afc7888157a9a4) with patch 82206 applied and i still
have the issue that sometimes my external screens turn to black and recover bit
later. Sometimes one does not recover at all or is flickering afterwards.

The dmesg log still shows some "[drm:gen8_de_irq_handler] The master control
interrupt lied (SDE)!" messages.

More sys infos here.
