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.

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.
