--- Comment #10 from EvaWang <evawang at linpus.com> ---
We tried latest drm-intel-next-queued from
http://cgit.freedesktop.org/~danvet/drm-intel/commit/?h=drm-intel-next-queued&id=68c8c17f527effba57f4e82efee18a249c6a1b58

it still can't enter to Desktop, LCD can't light on.

Could you give us some suggestion for this issue, is it related to LCD HW?
