The driver was coded expecting enough hardware queues and interrupt vectors such that at least there was one per socket. In the case where there were fewer than sockets, cpus were left unassigned thus null pointers. Rework the affinity mappings. Map settings for the cpu's that are in the irq cpu mask. For each cpu not in the mask, map to another cpu that does have a mask. Choice of the "other" cpu will attempt to map to the same cpu but differing hyperthread, or cpu within in same core, or cpu within same socket, or finally cpu in the base socket.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
