Pheew! I'm relieved :). We'll have to check if this patch is the proper fix for
all dce-8 or only a special case for kabini's dce-8.3. Maybe we should leave
the bug open until the final patch is decided upon and tested.

Thanks for the testing so far!

Yep, unrelated. This is another new bug introduced into kms-pageflip handling
