Re: F16/290.06: Unstable FPS on Xeon/470, working just fine on Athlon 635/210.
FWIW F17 / 295.53 / 3.4 exhibit the same problem. I've got a bad feeling this issue is scheduler related, but I have no idea how to test it. (Plus, given the use of binary drivers, I doubt that a kernel bugzilla entry will gain much attraction....)
