Kernel panic during a fullscreen video playback, maybe? That use case is likely to have an YUV FB as the only visible KMS plane FB, either primary or overlay plane depending on which is capable of displaying it. Sub-titles might not exist, or might be in a fairly small RGB overlay. I don't know if such case is important enough to handle. Thanks, pq
