I'm curious as to what happens if we just ignore the error and continue stress testing. You're right though -- we don't need an '030 for that (it's a non-fatal error). > But testing on 030 would be a good idea if you have one with enough RAM. My LC III has 36 MB which is sufficient for stress-ng. I will try it.
