Thank you!

I am currently testing on ubuntu budgie with valve-released Mesa-ACO and so
far, I am having no freezes nor crashes. Couple of days without incidents. But
as I posted previously, it is all a bit random so I think I will need to use
this for at least a week. 

I will report back soon with my findings.
