Yeah, it's definitely on my list. Basically if you hand videobuf2-vmalloc a piece of memory that is not page aligned, it gets treated as if paged aligned, which causes the first N bytes of every video frame to be garbage and the video is shifted right by N bytes. I saw the issue with both uvcvideo as well as em28xx. Devin -- Devin J.
