Why would that happen with the linux nvme stack that puts a completion queue on each CPU?

I think that in addition to allocating a queue per CPU, you need to be able to allocate a MSI(-X) vector per CPU. That shouldn't be a problem for the Samsung 980 PRO, since it supports 128 queues and 130 interrupt vectors.
