Hm, thanks. That's copied verbatim from your comment above. ;) I did not notice the inconsistency with the rest of the comments.
In the meantime I DID manage to disable APST with
sudo nvme set-feature -f 0x0c -v=0 /dev/nvme0
and that seems to have helped (no crash for 9 hours). I'll retry with 2000 now.
