You comment on the "amd76x_pm" module or all the tools to change the chipset behaviour to include idle tasks? So far I can report the amd76x_pm module doing not any problem to me. The system is rock solid under load (i.e. last night I did build the new FC3 kernel for my FC2, and prior other compilations). Temperature is going down in range of max. 20°C to 10°C when the module is loaded. What I observed - like Joerg Sommrey reported - are distortions in TV image running xawtv. So I am unloading the module if TV isn't just "background noise". Generally I load the module by modprobe.conf with options amd76x_pm lazy_idle=128 or set the lazy_idle value by hand with echo 128 > /sys/devices/pci0000\:00/0000\:00\:00.0/lazy_idle The distortion effect got better with change to current 2.6.11-1.14 kernel. Since 2 months running this module I had not any looking up of my system which is an ASUS A7M266-D board with the AMD SMP 760MPX chipset. And my machine is running day & night and often for about 14 days in a run. I tried other tools too and you are right Dave, some of them can cause a lookup even in moment you start the tool. That was the case for me when recently testing "athcool" http://members.jcom.home.ne.jp/jacobi/linux/softwares.html#athcool In general, the power supply must be quite stable as it might not like the frequent power consumption changes well.
