Certain boards with GP107/GP108 chipsets hang (often, but randomly) for unknown reasons during GR initialisation. The first tell-tale symptom of this issue is: nouveau 0000:01:00.0: bus: MMIO read of 00000000 FAULT at 409800 [ TIMEOUT ] appearing in dmesg, likely followed by many other failures being logged. Karol found this WAR for the issue a while back, but efforts to isolate the root cause and proper fix have not yielded success so far. I've modified the original patch to include a few more details, limit it to GP107/GP108 by default, and added a config option to override this choice.

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.
