[ Upstream commit 5a6254d55e2a9f7919ead8580d7aa0c7a382b26a ]
This particular Kioxia device times out and aborts I/O during any load, but it's more easily observable with discards (fstrim).
The device gets to a state that is also not possible to use "nvme set-feature" to disable APST. Booting with nvme_core.default_ps_max_latency=0 solves the issue.
We had a dozen or so of these devices behaving this same way in customer environments.
