Bug Description
Binary package hint: powernowd
The ondemand governor previously worked flawlessly with single core Sempron, after upgrade to dual core Turion the governor persistently ran cores at full speed with no load. Removing the ehci_hcd module immediately allows the ondemand governor to work as expected.
