My lemote.com email is too weak, I'll stop top post because this time I've
cc-ed my gmail.

I've tested, this patch can fix the nvme problem, but it can't be applied
to 4.19 because of different context. And, I still think my original solution
(genirq/affinity: Assign default affinity to pre/post vectors) is correct.
There may be similar problems except nvme.

By applying the very same patch perhaps?
