After a 1.5 days git bisect session it pointed me to this commit. :-) After reverting it (and some other patches of this series due to inter dependencies) it started working again. No further debugging on this from my side yet, as I just found it and wanted to let you know in case you have an idea what's going on. I will try to make some room this week to help with debugging and fixing. regards Stefan Schmidt
