with openSuSE 11.1 i could simply “rmmod uhci_hcd” to stop the cpu from whining (when changing in and off the c4-state caused by wakeups from the uhci-host-driver).
After installing 11.2, i recognized, that uhci_hcd is not compiled as module anymore but integrated into the kernel. Is there a way, to disable this driver with the same effect like unloading it in openSuSE 11.1 ?
