I experienced intermittent but frequent multi-second lags in X input, both keys and mouse on precise, using both the standard xorg and also the current one from the x-staging ppa. With help from raof, I discovered that turning off vt-d in the bios fixed the problem. So it seems like there is a bug in X to do with handling vt-d.
