If the HW throws a curve ball and reports either en event before it is possible, or just a completely impossible event, we have to grin and bear it. The first few events, we will likely not notice as we would be expecting some event, but as soon as we stop expecting an event and yet they still keep coming, then we enter into undefined state territory. In which case, bail out, stop processing the events, and reset the engine and our set of queued requests to recover. The sporadic hangs and warnings will continue to plague CI, but at least system stability should not be compromised. v2: Commentary and force the reset-on-error. v3: Customised user facing message for forced resets from internal errors.

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.
