I prefer to dig into this a little bit more, as I don't really understand it. Set the videobuf2-core debug level to 1 and see what the warnings are. Since 'buf.qbuf' fails in v4l2-compliance, it's something in the VIDIOC_QBUF sequence that returns an error, so you need to pinpoint that. If push comes to shove I can also merge the patch without USERPTR support, but I really prefer not to do that.
