Does the RTAI/kernel version make the difference here or the RTnet version (or git revision)? > > Thanks a lot for your answers so far. I hope the dump can give you a > clue of the problem. Not yet. Maybe we see an early shot of the rtcap_signal_handler, maybe it's a so far undiscovered race. Can you retry with CONFIG_FRAME_POINTERS enabled, and maybe also CONFIG_IPIPE_TRACE_MCOUNT (selects frame pointers automatically)? The latter may provide a better picture of what happened before the crash (increase /proc/ipipe/trace/back_trace_points to, say, 1000 before triggering the oops.) Thanks, Jan
