This is enough for now. The problem is that a USB transfer is started but never stopped, which indicates a problem with the host controller. In this case you're using an xHCI host controller. Unfortunately the xHCI maintainer is on vacation, so he won't be able to help for a while. In the meantime, you could try doing a git bisection to find which commit caused the problem to occur.
