In this error message:
BUG: unable to handle kernel paging request at ffff8804c001fade
Is ffff8804c001fade the physical memory address or virtual memory address?
Since I doubt you’ve actually managed to put 16 exbibytes of RAM into your server, logic demands that it’s a virtual address.
Indeed, in older kernels the message actually explicitly stated “unable to handle kernel paging request at virtual address ########”…
