I'll let the AMD people answer this.

Bugs are always a part of life, the fact that we fix them is what is
important.

This woried me, as I don't recall anyone notifying me of it. Then I saw
your revert, and I noticed that all you really need to resolve this is
commit id ec95d35a6bd0047f05fe8a21e6c52f8bb418da55 to be added to the
tree. I'll go queue that one up for the next .32-stable tree.
So all should be resolved now, right?
thanks,
