The apitrace no longer causes issues on my system either if I use
AMD_DEBUG=nodpbb . I also decided to try this on minetest and *so far* (bearing
in mind the issue was indetermistic in the first place, so a decisive ruling is
near impossible) I have not re-incurred a crash.

Interestingly, what I have noticed is that sometimes when minetest did not lock
up my system before, the loading bar would suffer mild graphical corruption
(bits of the black border go white) - quite difficult to capture on camera due
to being so fleeting. So far with nodpbb I have yet to observe these artefacts
again.

I did try launching a minetest world with AMD_DEBUG=check_vm instead, however I
somehow still managed to get a lock-up that way with similar graphical
corruption as the bug description. Alas it seems my btrfs root decided to eat
my dmesg log file when I had to force power off, so unable to see if it was the
dreaded VM_L2_PROTECTION_FAULT again >:(
