Often, such plain lock-ups point to IRQ conflicts of the RT subsystem with Linux (though Xenomai 2.3 should tell you about this). Please check your hardware setup (/proc/interrupts, /proc/xenomai/irq). Does the lock-up also happen when you configure RTnet manually for TDMA-less operation and call "rtroute solicite ..." e.g.? If the issue remains unexplainable, please repeat your precise current setup (used kernel/Xenomai/RTnet versions, kernel config, RTnet setup). Jan
