This one looks really weird to me. dev.ichss.0.freq_settings: 1397/-1 -1/-1 This says that you have two CPU speeds, 1.397 GHz and -1. ???? Worse, this system is a Celeron-M. I am not terribly familiar with the Celerons, but I thought the Celeron-M supported EST, not ICHSS. Why do you not use est? It's much more powerful than any other power management technology. Can you post a full DMESG? I'm curious what the device probe is picking up. Something looks bogus. I'm just not sure what. Is someone else running a Celeron-M system on current? What do you see for 'sysctl dev.ichss' and 'sysctl dev.cpu.0'? I have a hunch that the system is not probing correctly and really does not do ICHSS. -- R.
