I did some quick testing and it seems this happens on whatever loop device that had a file attached and then detached. No matter if it's the next available or not. So, if you create a new loop device without ever attaching a file to it, it seems the block layer is not setup sufficiently so any requests will really go through it. But when it is attached, then detached, the block layer still sends requests to the loop driver, which will result in the EIO as it is detached.
