core dump analysis

(In reply to Mina Galić from comment #3)

Kernel panic resulting from: 

kldload amdgpu

Dump header from device: /dev/ada0p2
  Architecture: amd64
  Architecture Version: 2
  Dump Length: 371363840
  Blocksize: 512
  Compression: none
  Dumptime: 2023-06-13 07:05:45 +0100
  Hostname: fuji
  Magic: FreeBSD Kernel Dump
  Version String: FreeBSD 13.2-RELEASE releng/13.2-n254617-525ecfdad597 GENERIC
  Panic String: page fault
  Dump Parity: 1984728343
  Bounds: 0
  Dump Status: good

<https://bsd-hardware.info/?probe=f6540a4d85> – whilst this hardware does not
include AMD graphics, I assume that we should be able to load the module
without the kernel panicking.
