Comment # 15 on bug 1193640 from Felix Miata

Upstream issue 4150 was dup'd to issue 4762.

https://gitlab.freedesktop.org/drm/intel/-/issues/4762 just had added the
following:

"git://github.com/vsyrjala/linux.git dbuf_sanitize might be sufficient
workaround for this. Please test."

Can anyone here provide a translation, or better yet, a BS solution to
facilitate testing?
