When the KMD sends a CLIENT_RESET request to GuC (as part of the suspend sequence), GuC will mark the CTB buffer as 'UNUSED'. If the KMD then checked the CTB queue, it would see a non-zero status value and report the buffer as corrupted. Technically, no G2H messages should be received once the CLIENT_RESET has been sent. However, if a context was outstanding on an engine then it would get reset and a reset notification would be sent. So, don't actually treat UNUSED as a catastrophic error. Just flag it up as unexpected and keep going.

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.
