Tested on a HP-Compaq nx9005. acpi - You need to boot with acpi=on (you didn't specify whether you did this or not), and also need recent initscripts so that the relevant modules get loaded. cpufreq - the kernel doesn't actually do anything other than provide an interface to userspace. You can adjust the speed using /proc/cpufreq I booted the system with acpi=on. cat /proc/cpufreq has no dataline. If I "echo %0%40%100powersave > /proc/cpufreq" and do the cat again no new dataline is added. cat /proc/cpuinfo shows: processor : 0 vendor_id : AuthenticAMD cpu family : 6 model : 10 model name : mobile AMD Athlon(tm) XP2400+ stepping : 0 cpu MHz : 1788.873 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 sep mtrr pge mca cmov pat pse36 mmx fxsr sse syscall mp mmxext 3dnowext 3dnow bogomips : 3565.15 what does /proc/cpufreq show ? [rob@mars rob]$ cat /proc/cpufreq
minimum CPU frequency - maximum CPU frequency - policy

You don't have the powernow-k7 module loaded. The powernow-k7 module shows up at /sbin/lsmod... If I use the command echo -n "0:50%90%powersave" >/proc/cpufreq it does nothing, but using : instead of % and Khz instead of percentages it works. still a problem in fc2/fc3 ? With fc3 everything is OK. |
Description of problem: Acpi and cpufreq won't do their job on an Athlon XP-M; the coolervan blows at topspeed because the cpu runs at topspeed too. Version-Release number of selected component (if applicable): How reproducible: Always after boot. Steps to Reproduce: 1. Boot system. 2. 3. Actual results: Expected results: Additional info:
