--- Comment #2 from Chris Wilson <chris at chris-wilson.co.uk> ---
The unknown is from sna_output_detect() calling DRM_IOCTL_MODE_GETCONNECTOR on
an invalid connector. The output should have been disconnected by the hotplug
notification... except that you do not have udev monitoring compiled into your
ddx (or it failed to be initialised). In the short term, check your build to
see why udev is not configured. My challenge is to handle it more gracefully.
