It works for threads that are running and are in stop (at least the stop0_lite state enabled in DD1). Comments on the OPAL patch in particular would be good. Next step will be more testing with DD2 and different idle states. This was taken mostly from pdbg but I have ended up changing a few things (e.g., to make it work in idle state). Thanks, Nick
