What I have found out there was, that the system freeze happened always whe= n trying to start a thread (in the original application, the tasks run fairly long). I think it has to do with rt_task_start() followed by usleep() and the non-= realtime stuff running on CPU 0 and the realtime stuff running on CPU 1. I never saw that issue on a single core CPU (even if the same SMP kernel wa= s used). Regards Mathias > M.
