Are they exactly the same kernel? Also, even though you're back to using crash-5.0.1 again, I afraid I can't even speculate as to what would cause the machine to freeze, nor have I ever seen such a thing happen before. Perhaps the /dev/mem driver read something it should not have based upon a faulty virtual address? I don't know... > > Does this problem something related to hardware / bios configuration? > I am providing the details, if by any chance it helps you: Sorry no, that doesn't help. If you can't even get crash running on a live system, then I'm running out of suggestions.
