Ok, just for future reference, this information is like 10x more important than 
*any* of the other information you presented in various changelog versions of 
this patch! I do not have this hardware so i had no idea how severe the problem 
was in practice - whether it's cosmetic, performance related or stability 
related.

I'll push your urgent fix to Linus via tip:x86/urgent.

Thanks,

	Ingo
