I notice the problem in Puma (10.1) It seems there is some timer error?, as e.g., the time remaining for installation fluctuates like crazy (1600 hrs to go), and the beachball spins like mad. At boot there is a too rapid succession of “still waiting for boot device” . Just guessing, but might a timing issue also explain the slowness of Leopard?
Possible. I'm not really sure, I haven't had too much of a chance to investigate but it's quite possible that there's a problem with time base calibration.
Though the VIA part of the PMU is identical to the CUDA part (unless I missed something up ...)
Regarding Leopard, I think that it's just slow :-) I installed it on my old Mini G5 and it's definitely much slower than Tiger accross the board.
Chers, Ben.
