I have a system that's behaving as though it's under a moderate load, but nothing's happening and the load average is zero. If I change my cpufreq governor to 'conservative' or 'ondemand', the CPU immediately scales up to the maximum clock frequency (as though something was demanding that much power). The system is also very warm, which is abnormal even when the machine is always clocked at its maximum frequency.
Top shows that there are no processes which are hogging the CPU, and /proc/interrupts doesn't reveal anything interesting (i.e. an interrupt storm). The only way to get my system to stay cool is to change the cpufreq governor to 'powersave' or 'userspace' (and then clock it at the lowest, manually).
I've tried 2.6.31.1 and Linus' current git tree (2.6.32-rc1-301-gf0a221e). My configs are attached.
My system is a MacBookPro2,2. I'm running an x86_64 kernel.
Any ideas of what could be going on? Am I missing something horribly obvious?
