 I'm willing to revert/test code on my machine, problem is I don't know 
sequence nor what I can safely revert. I haven't messed with video 
drivers/code since DOS days of having to write ones own graphics 
routines. I could force? kernel to build with '-g' on drm/amdgpu? and 
walk it I guess. But don't know what I'm looking for. :(
