-Subject: [PATCH 28/51] dell/3050micro: disable nvme hotplug
-
-in my testing, when running my 3050micro for a few days,
-the nvme would sometimes randomly rename.
-
-e.g. nvme0n1 renamed to nvme0n2
-
-this might cause crashes in linux, if booting only from the
-nvme. in my case, i was booting from mdraid (sata+nvme) and
-every few days, the nvme would rename at least once, causing
-my RAID to become unsynced. since i'm using RAID1, this was
-OK and I could simply re-sync the array, but this is quite
-precarious indeed. if you're using raid0, that will potentially
-corrupt your RAID array indefinitely.
-
-this same issue manifested on the T480/T480 thinkpads, and
-S3 resume would break because of that, when booting from nvme,
-because the nvme would be "unplugged" and appear to linux as a
-new device (the one that you booted from).
-
-the fix there was to disable hotplugging on that pci-e slot
-for the nvme, so apply the same fix here for 3050 micro
