Once FW raised an event following a MME2 QMAN error, the driver should have gone to the corresponding status registers, trying to gather more info on the error, yet it was accidentally accessing MME1 QMAN address space. Generally, we have x4 MMEs, while 0 & 2 are marked MASTER, and 1 & 3 are marked SLAVE. The former can be addressed, yet addressing the latter is considered an access violation, and will result in a hung system, which is what unintentionally happened above. Note that this cannot happen in a secured system, since these registers are protected with range registers.

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.
