dmesg: disable eDP
(In reply to <a href="show_bug.cgi?id=69248#c1">comment #1</a>)
<span class="quote">> Ok, I think we should track the "*ERROR* mismatch in clock" error here (the

If eDP disabled, no matter whether VGA enabled or not ,there's also call_trace
and error, but "[drm:intel_pipe_config_compare] *ERROR* mismatch in clock"
disappeared.
