Bus errors with almost-random behaviour are typical of marginal
No mantra here, just sticking with the explanation that's the most
probably one matching a specific description.
A VM abort doesn't fully exclude bad hardware.
To convince the last sceptic, you could run the same VM on two different
hardwares (make them as different as possible, i.e. different build
years, different vendors, different models of main board / RAM).
That would exclude the possibility that the VM maps its virtual RAM to
the always same faulty real RAM cell (or some other unknown faulty
behaviour). It would certainly exclude all hardware failures that I
could imagine :-)
