Incredibly high chance that the answer is yes.
I don't recall any patches that could affect this, and in honesty filing
this at rh bugzilla is going to make me scratch my head, and then
ask people here like tglx & ingo to take a look, so other than for tracking
purposes, it's not likely to improve chances of it getting fixed.
