Please report this upstream at <https://bugs.freedesktop.org/> under product 'DRI', component 'DRM/Intel'. But before you do that, you should gather some more debugging information from the driver: boot with the added kernel parameter 'drm.debug=0xe', try to enable the HDMI monitor, and then save the output of dmesg. Let us know the URL of the upstream bug report so we can track it. Ben. -- Ben Hutchings We get into the habit of living before acquiring the habit of thinking. - Albert Camus
