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? Thanks, tglx
