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.
