Re: RTAI in debian9

May you try the "testsuite/user/latency" test, in your RTAI install dir, after saving and substituting the existing "run" script with the one below and then let me know what happened? 
Do it on an unloaded machined and, if possible, after seeing a stabilized average latency, attach to your answer also a short snapshot of what appears on the screen.
Thanks, Paolo

Hi again:

I have test a simple program obtained with rtai-lab  (scicoslab version), monitoring with qrtailab and the system is working.

I have load rtai_sched with kernel_latency=1000 and user_latency=1000
