I can't help with debugging on RTAI, but I can provide the usual hints how to approach such problems: - redirect kernel messages to a serial port in the hope that some error messages are issued on/around the freeze - compare your kernel .config with the other systems that work - try to narrow down the trigger for the freeze my simplifying what RTnet does (rtnet -v will dump all command issued during startup, so that you can replay them manually) - use printk debugging techniques to further narrow down the trigger - discuss findings here and probably also with the RTAI community Jan
