With amdgpu and CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS=y, there are errors like: BUG: non-zero pgtables_bytes on freeing mm and: BUG: Bad rss-counter state with TTM transparent huge-pages. Until we've figured out what other TTM drivers do differently compared to vmwgfx, disable the huge_fault() callback, eliminating transhuge page-table entries.

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.
