The nvme-fc transport may call to abort an io on controller reset. If the driver is out of resources to issue an abort command, it just gives up and does nothing. The transport expects the lldd to always be able to terminate an io it has issued. At that point, the controller hangs waiting for aborted ios to be returned. Note: flaged by "6136" and "6176" error messages. Root issue was the adapter mis-allocated the number resources it allocated for command entries for the adapter. Convert the driver to allocate command resources based on the number of xris supported by the FC port - 1 resource for the original command and 1 resource for the abort request.

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.
