Okay, these 4 patches fix the issue, but they also refactor the code and so a lot more. They are not suitable for stable kernels, so to just fix the issue I take the small patch I extracted from yours and posted previously. I retains your authorship, hope that is fine with you. You can rebase these patches on-top of that minimal fix. Joerg
