Plus there are some OHCI updates in the USB patches (you'll have those in the MM tree) that help address some of the more perverse ways that suspend-to-disk kicks USB around, and a few similar usbcore changes that need re-integration with the RC3 swsusp/pmdisk updates. Keep using the "rmmod" workaround for now. And don't combine CONFIG_USB_SUSPEND with suspend-to-{disk,ram} unless you're feeling like debugging the results. - Dave
