Keyboard response, mouse movements, display refreshing etc. General input/display sluggishness. Did something break IRQ handling somewhere?

Does either of the kernels in question have commit 0f815a0a700b (USB: UHCI: fix IRQ race during initialization)? That commit was added to fix precisely this sort of thing.
