There are reactions in this thread that contradict your 'anyone else' point.

Except you are missing that the hang (and the first crash as well) happens on
brand-new user-space just as much - not just on 'old userspaces'.
The bugs i've triggered are independent of any user-space component - it
happens with a fresh distro just as much.
As i suggested before, at least the text should be updated to include what
has been written about CONFIG_DRM_RADEON_KMS in this thread before:
