[ 2032.194376] nvme nvme0: failed to connect queue: 9 ret=-18

queue 9 is not mapped (overlap).
please try the bellow:

This seems to work.  Here are three mapping cases:  each vector on its
own cpu, each vector on 1 cpu within the local numa node, and each
vector having all cpus in its numa node.  The 2nd mapping looks kinda
funny, but I think it achieved what you wanted?  And all the cases
resulted in successful connections.

Thanks for testing this.
I slightly improved the setting of the left CPUs and actually used 
Sagi's initial proposal.

Sagi,
please review the attached patch and let me know if I should add your 
signature on it.
I'll run some perf test early next week on it (meanwhile I run 
login/logout with different num_queues successfully and irq settings).

Steve,
It will be great if you can apply the attached in your system and send 
your findings.

Regards,
Max,
