Maybe. But then again, as someone who dual boots, I see one of the OS crashing and giving an alround worse experience then the other, on the same exact hardware, while the other just chugs along.
Now, I'm not someone good at maths or physics, so maybe, somehow, it's actually more likely than not that the worse OS gets to run when there's worse solar activity going on or whatever else has en effect on my hardware, which also doesn't seem to affect memtest for some reason.
But the likelihood can't be that high. Can it?
It could easily be flakey hardware and different drivers. Not necessarily better or worse, but one driver cause the hardware to ocassionaly fail in exciting ways, like DMA to the wrong address if jusy the right access patterns happen.
If you've got an IO-MMU and everything aligns properly, devices can't DMA to the wrong place anymore, which might make it easier to track things down.
