Seems to be a well known bug in Ubuntu Jaunty! See these threads http://ubuntuforums.org/showthread.php?t=1135055 https://bugs.launchpad.net/ubuntu/%2Bsource/linux/%2Bbug/355155 https://bugs.launchpad.net/ubuntu/%2Bsource/linux/%2Bbug/375986 a lot to read. I solved my problem be recompiling kernel 2.6.27 (see here for a guide http://ubuntuforums.org/showthread.php?t=311158 ) but had yet no luck to do the same with the real time kernel from Jaunty.
