I've managed to get it to boot by commenting out the counter increment, which might work
as a quirk:
Great, that's essentially what I proposed in a different thread (sorry, I see
now you were not copied there):

  http://lists.infradead.org/pipermail/linux-nvme/2021-September/027665.html

The final patch may look a bit different, but it should be okay to test with
the one in the link.
I've tried that patch, it doesn't crash, but /dev/nvme0, /dev/nvme0n1 etc don't show up so
it doesn't progress past the initramfs. There weren't any errors other than preexisting
acpi table ones.

(I sent this a few minutes ago but I forgot to reply all so here it is again)
