Does the samsung issue also exist in CSM mode?

performing exactly the same series of accesses on some modern Samsung laptops gives an uncorrectable machine check exception (in the best case) or destroys your firmware (in the worst case).

Does this mean the issue is only with samsung-laptop or are there other parts of the kernel that will also cause these issues?

Does turning off UEFI (and switching to CSM/legacy mode) stop this problem?
