Please, could you run top command while you're tuning on the switch and tell us if the is one process that use all the CPU ?
Would you be willing to test the latest pre-release of Jaunty - http://cdimage.ubuntu.com/releases/jaunty/ . You should be able to test via a LiveCD. It would be helpful to know if this trouble exists in the upcoming Jaunty release. Please let us know your results. Thanks.
