From 5a6254d55e2a9f7919ead8580d7aa0c7a382b26a Mon Sep 17 00:00:00 2001 From: Enzo Matsumiya Date: Fri, 5 Nov 2021 23:08:57 -0300 Subject: [PATCH] nvme-pci: add NO APST quirk for Kioxia device 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.
