[arch-general] high CPU temperature with 2.6.32

Hello, pacman just brought kernel 2.6.32 for my old laptop (P3 500MHz). A strange thing I noticed is that the fan won't go off when CPU is idling like it used to. Using powertop I can see more than 100K wakeups/s (extra_timer_interrupt is first on the list but I think it's irrelevant since it only shows about 100 wakeups), and the CPU is not going into C2 mode at all. Strangely however the cpu is 99% idle, and top doesn't show "system" or "user" cpu usage. Anyone else seeing such behaviour? Thanks in advance, Dimitris
