Oh, and suspend now works for USB devices, thanks to Paul :) And on some systems, the resume path even works ... :) The D3cold resume path -- which should behave very much like resuming from software suspend -- can be made to self-deadlock in some cases: dpm_sem is held while the resume callbacks are made, so they deadlock when calls to device_del (for getting rid of the old device tree) try to grab the same lock. So don't get your hopes up too far yet -- but yes, that usbcore patch does help some configs a bunch. - Dave
