According to the Serial ATA AHCI specification, Device Sleep is an optional feature and as such no errors should be printed if it's missing. Keep informing users, but use dev_info() instead of dev_err().
Does this condition actually occur? The cap's advertise that the controller does DEVSLP but the port register doesn't have it? Thanks. -- tejun
