<pre>It's enough, or rather we do not log anything else that is relevant. Frequent
hotplug events causing EDID reads which occasionally fail and so rendering the
output disconnected.
A workaround would be to save the valid edid and then force the kernel to use
that via the drm_kms_helper.edid_firmware= parameter. But before doing that, I
would try replacing the DVI cable.</pre>
