Testing on 68060 hardware could be helpful (not emulators though). If the NOP failed to solve the problem on some CPU device or other then we could look for a more broadly applicable solution. I suppose there may be a faster solution too. Perhaps an architecture expert could comment. > I just need to run the stress-ng --sysbadaddr -1 thing before and after > and collect the logs? > That would work. I've been using an old static build of stress-ng 0.12.12 but I imagine that newer versions would be just as effective. Note that the stressor runs for one day by default. You can use ^C or set a different duration with -t N.
