Well, that is rather old hardware. I suggest to make sure first that the 
hw isn't broken in some way.

You first need to figure out what's the failing component. Either Mesa, 
DDX or the Kernel are possible candidates.

Another possibility is that you updated kodi and kodi is now doing 
something the hw doesn't like.
