[Bug 90804] System "forgets" about its DVI output

--- Comment #8 from Chris Wilson <chris at chris-wilson.co.uk> ---
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.
