(If not disabled, it is possible that your system may hang with low Cx states.) Have you set economy_cx_lowest and performance_cx_lowest to "Cmax" (or "LOW")? Check "sysctl dev.cpu.N.usage" to make sure that los CX states are used. (N is the CPU number.) Unless you are running a CPU intensive program, most time should NO be in C1 and should be in you lowest Cx state. Also note that on many systems you will have more and lower Cx states available when on battery. (I think this is REALLY dumb, but the BIOS writers must have some reason for it.) Is your heat sync clean! I see temperature increase by 10C or more when it gets dusty and it seems to be almost a step function. Seems fine and then, quite suddenly, it gets hot. Check your dmesg and make sure PowerNow (or whatever AMD calls EST) is enabled. The ONLY two features that really are sugnificant to power management is Cx states (most important) and EST/PowerNOW (voltage/true frequency). -- R.
