The NMI watchdog (Realtime) kernel parameter in the kernel configuration wa= s accidentally disabled (perhaps because I tried in between with a non-APIC I= RQ). Now I have again the error situation of this morning: Even with gcc-3.3 I am not able to load the xeno_native module when NMI wat= chdog is enabled, the system directly reboots (without printing to the serial con= sole) The printout I have sent before was the printout of the standard linux NMI = but not of the Xenomai NMI. I.e., it seems _not_ to be the reason of the compiler that leads to the beh= aviour! Regards Mathias > M.
