Hi, I am working on getting this solved and a couple of questions have arisen: 1. who is responsible for resuming a device when a command arives? the storage driver or sd? If sd the problem is that sd doesn't know when a host can suspend attached disks. 2. Do commands need to be marked for relating to PM tasks?
