To follow-up. Earlier today I fresh-booted and didn't use the APST disable command - my machine crashed out with read-only errors after minutes.
I then updated grub to use `nvme_core.default_ps_max_latency_us=250` as suggested - it was stable for 6 hours, through 2 suspends. A little while ago it crashed with read-only errors.
I'm now going to try `nvme_core.default_ps_max_latency_us=0` in GRUB.
