Are you using ACPI? I was using before this experiment, but I recently switched to APM so I had to disable that one to get speestep to work. > Mine is a GM855 + pentium-M 1500 and I'm using kernel 2.6.9-cko3. > > Despite it shows 400mhz in /etc/cpuinfo, 600mhz are shown > in /sys/devices/system/cpu/cpu0/cpufreq/ as the actual speed value. 400mhz > appears in available speeds, so does in scaling_min_freq and > cpuinfo_min_freq. I have this interesting behaviour: if I don't look into /sys/devices/system/cpu/cpu0/cpufreq/, then the speed (as reported by the gnome-applet) is 28% (that is 400MHz) but as soon as I cat /sys/devices/system/cpu/cpu0/cpufreq/* then the kernel resets the minimum to 600 MHz (and tells me about it in the kernel log). > CONFIG_X86_PM_TIMER=y makes the message "losing tics" dissapear; it still > shows (2 times in 20 minutes) the following messages (dmesg output): > - ----- > Warning: CPU frequency out of sync: cpufreq and timing core thinks of 400000, > is 600000 kHz. > Warning: CPU frequency is 400000, cpufreq assumed 600000 kHz > - ----- When that happens, the speed is indeed reset to 600: I use powernowd so the speed goes down to mimimum automatically working around this periodici resets. ciao graziano > Anyway it seems to work...
