From the dmesg log it seems that we can't get the correct EDID for LVDS and then it complains the following warning message:
   >drm:edid_is_valid] *ERROR* Raw EDID:

At the same time it seems that the system will check the state of LVDS and then try to get the supported mode periodically. But as it can't read the EDID correctly.

Maybe we should avoid to read the EDID for LVDS on this box.

Please attach the output of vbios.dump and dmidecode.

Thanks.
