I also tested with 10-CURRENT kernel, downloaded from an ftp mirror on May 5th, 2013. This kernel showed the same behavior, so I did all further testing with the 9-STABLE version. I will update my sources to 9-STABLE first thing next weekend, and will also re-test with an up-to-date CURRENT kernel. Klaus
