Let's track the first issue here. It seems the second issue has been tracked at bug#28579.

I fail to access http://www.mail-archive.com/intel-gfx@lists.freedesktop.org/msg00381.html. Can you give another url or paste the content here?

Thanks. I can access this. That issue has already been tracked at bug#28224, so I'm marking dup here.
