  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I'm not surprised you get a kernel panic with this system. Your RAM has
faults.  Unless you're absolutely sure this is not the case and the NMI
complaint is bogus (I see you've tested with various other OSes, and
even then it might be true) I suggest swapping RAM and trying again.
