So you're sending a patch for which you have absolutely no justification? And
CCing it to stable too?

And that patch hasn't been tested to actually address anything?

Just a wild hunch?

I wouldn't do that in the future if I were you.

HTH.

I don't have an AMD machine to test this on. I spotted something
that looked wrong in the code and sent it out to see what others
think.

Maybe I'm reading the manual wrong, but is raising a concern
based on the code and the manual really just "a wild hunch"?
