Yes, this is the reason for it. Actually, only the first freeze has any effect, later calls will be ignored. Hmm, I though to remember some issue of the Xenomai-side patch when tracing was disabled but I cannot reproduce this issue again (was likely related to other hacks while tracking down the PREEMPT issue). So from my POV that patch is ready for merge as well. Jan
