A kexec reboot causes the controller fw to assert. This assertion shows up in two ways, the controller doesn't show up as ready and an interrupt is waiting as soon as the handler is registered. To resolve this added below fix: - Split the interrupt handling setup into two parts, setup and request. - If the controller ready register indicates not-ready, but that the not readiness is only on the IOC units we can still try a reset to bring the system back to the pre-reboot state.

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.
