I don't have a clue as well. I just verified (almost) your scenario against a 2.6.15.5 kernel with gcc 4.1 and 3.3 and Xenomai trunk. No problems here. Please try from scratch with all components (kernel+xeno and rtnet), collecting the configure and build output of RTnet. If things then still go wrong, please send the collected output + your .configs (kernel + rtnet) to me privately. Jan
