Failure of that assumption is the heart of the whole "regression" discussion. It's not limited to hardware, kernel security might be an issue, some network protocols might work faster and less reliably, etc.

Kernel behavior changes sometimes totally break user software which makes unwarranted assumptions. That's not a regression, although users may see it that way. When a change in fork() changed the child-runs-first behavior, many programs broke, as was true with threading changes. Bad reliability is the reward for bad code, but if a kernel change makes that obvious some people think it's a regression.
