Hello all, My realtime system experiences periodic bursts every 4 hours. How can i find the reason for this ? I know the traceit tool but it dumps so much data and it is useless under this case. I need to find what happened at the exact time of burst. I use rtai_smi module to disable SMI interrupts and set my network interface driver priorities to 99. So it should be something non maskable but what ? Sinan. Ömer Sinan Kaya (M.Sc.)
