Hi Jan and Gilles, after a long debug-reboot-try-again-session I was able to reduce the problem I had to a very short application that leads to a complete system freeze on a 2.6.19.1 kernel. As with my PC I am not able to run the NMI stuff within Xenomai, I forward the application to you and the list. Perhaps somebody can try out the enclosed application with the latest Xenomai version on 2.6.19.1. Please adjust the IP settings in the C file and in the xenorun script to your setup. It is sufficient to send out UDP frames, if the remote device does not answer this does not hurt. However the remote device should listen on a specified port to avoid ICMP complains about no-opened UDP ports... Using Ethereal I monitored the traffic. Here is the summary of it: ARP request/response (from the xenorun script) ARP request/response (from the applicaion) UDP message to port 18765 (no answer) 2 seconds later: UDP message to port 18765 (no answer) 2+5=7 seconds later: ARP request/response (from the application) 2 seconds later: UDP message to port 18765 Here the system freezes. I do not see the message "Step A".
One important piece is the system() call out of the realtime application to do a rtroute. When I remove this call, there is no error... I am using Xenomai SVN #1969 and the included 2.6.19.1 patch. Pentium 4 UP. Any feedback on this is highly welcome! Regards Mathias -- Mathias Koehrer [EMAIL PROTECTED] Viel oder wenig? Schnell oder langsam?
