Hi @weileng

As I already told in another post. For any kind of orin display issue, please test on Orin devkit first.
DCE means display controller engine, which is still related to display setting.

Also, does this cause anything go wrong there?

Hi @WayneWWW

It’s one error message during system suspend procedure, which won’t lead to kernel panic. So in common case, what case will trigger such error? Thanks.
