I already tested the p4-clockmod.ko just now. both is outputted same message: (do again) ------------- dump of screen ------------ # modprobe acpi-cpufreq.ko FATAL: Module acpi-cpufreq.ko not found # modprobe p4-clockmod.ko FATAL: Module p4_clockmod.ko not found -------------------------------------------------- I first tried the acpi-cpufreq.ko because the module is recommended by kernel 2.6.20+. After not effect, I also tried the p4-clockmod.ko since my machine is intel processor: -------------------- dump of screen ------------------ # cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Pentium(R) Dual CPU E2200 @ 2.20GHz stepping : 13 cpu MHz : 2194.384 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good pni dtes64 monitor ds_cpl est tm2 ssse3 cx16 xtpr pdcm lahf_lm bogomips : 4388.76 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Pentium(R) Dual CPU E2200 @ 2.20GHz stepping : 13 cpu MHz : 2194.384 cache size : 1024 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 apicid : 1 initial apicid : 1 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good pni dtes64 monitor ds_cpl est tm2 ssse3 cx16 xtpr pdcm lahf_lm bogomips : 4388.78 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: --------------------------------------------------------------- And, I grep the "est" in /proc/cpuinfo, and it is there. so, the cpu hardware should have opened the support.
