Yes, I am certain - this is information right from the CPU designers. When I did modify the signal frame for PMC's E9000 core I knew some software such as debuggers was likely to break, so I was careful to only use the mechanism if absolutly necessary that is on E9000 cores. The problem semmed to strike rather frequently on E9000 but there had been no reports of application crashes matching the problem's fingerprint on RM7000 so the issue felt as if it was rather theoretical on RM7000. So I choose to not enable the workaround for RM7000 until recently. Ralf
