On debian (4.9) I didn't notice the issue but I didn't use much. HOWEVER, when I do apt-get upgrade on debian I do get the issue. It just updated the kernel file, didn't run the new kernel (a boot would have to happen).
On v4.15 I didn't change the nvme_core.default_ps_max_latency_us=0, I guess. I did before upgrading to v4.15, I guess. But I can try again.

This is all very strange
