nVME crashes system

[belfastraven]

Do you know the command for verifying that apst is enabled and working?

 from Arch Wiki
assuming you have nvme-cli installed:

sudo  nvme get-feature -f 0x0c -H /dev/nvme[0-9]

should be good for any kernel >= 4.11 

I have a mydigital SBX eco (80--so I hacked off part of the adapter with a hacksaw...).  which is a low pwer dramless device and has been running well for weeks now.    It shows APST enabled.....   I don't notice any extraordinary power usage even when running disk tests.   I'm running on Manjaro, using the new SPI mainline Flash, booting the EMMC with root on the NVME.

I run a Samsung pm981 on a rockpro64,  and its gets hot enough that I decided it wouldn't be a good candidate for the notebook.   I thought that Sabrent had also dramless disks,  but couldn't find a single-sided one.
