Re: Re: [Xenomai-help] Howto catch SEGV signals in Xenomai

Hi Philippe,

I tried with nmi_watchdog
However with nmi_watchdog=1 I am not able to load my module xeno_native as 
the PC resets during the modprobe command...
I remember that I had this strange issue a while ago with the 2.6.19 kernel...

With nmi_watchdog=2 I can modprobe xeno_native, however I do see any change.
The PC is still freezing.

Regards

Mathias
