The aux timeouts that we have seen previously in case of eDP panels could be because the panel is not really ON when we try to link train and that can happen because the panel power cycle delay is not long enough. Could you please try the attached patch that increases the panel power cycle delay to see if that fixes the issue and also send a dmesg log with drm.debug = 0xe?
