However, it looks as if I do not understand the NMI watchdog correctly... I passed nmi_watchdog=3D1 as kernel parameter. Now, the NMI watchdog seems to be o.k. I have set the kernel parameter "NMI watchdog latency threshold (us)" to 10= 00000 (1 second). Now I do a modprobe xeno_nucleus. This is o.k. Then I do a modprobe xeno_native. This leads to a watchdog NMI on the console after 1s. "NMI watchdog detected timer latency above 100000us" CPU 1 EIP is at mwait_idle 0x23/0x37 When I compile the Xenomai functionality directly into the kernel (no modul= es), I never reach the login prompt at my PC as the NMI watchdog from above came first... Well, somehow the NMI stuff seems to work. However, I am not able to start = my application as my systems gets the NMI before I have the chance to start the applicatio= n... What is wrong here? I think, I miss one piece in the puzzle... Thanks for any support on that strange behaviour. Regards Mathias ----- Original Nachricht ---- Von: Gilles Chanteperdrix An: "M.
