The mtip32xx driver uses managed resources for DMA coherent memory and irqs, but then always pairs them with free calls anyway, making the resource tracking rather pointless. Given some DMA allocations are transient anyway, the irq freeing seems to require ordering vs other hardware access the best solution seems to be to stop using the managed resource API entirely.

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.
