FWIW, this appears to work around the issue: Create file /etc/udev/rules.d/90-nvme-power.rules : --- KERNEL=="nvme*[0-9]n*[0-9]", ATTRS{model}=="SAMSUNG MZSLW1T0HMLH-000L1*", ATTR{device/power/control}="on" ---
On my system at least. I'm sure the kernel should somehow blacklist settings that bakes certain devices behave erratically, but until then, this appears to do the trick.
