This is more or less a basic fileserver that also does some compilations from time to time. cat /proc/cpuinfo from 2.6.24.2: processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 1 model name : Intel(R) Pentium(R) 4 CPU 1.70GHz stepping : 2 cpu MHz : 425.000 cache size : 256 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 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 pebs bts sync_rdtsc bogomips : 3401.38 clflush size : 64 scaling_available_frequencies (p4-clockmod): 425000 637500 850000 1062500 1275000 1487500 1700000 Since the server is idling most of the time I enabled the ondemand governor and installed p4-clockmod. I read that this is not the best solution but acpi-cpufreq is not working for me. Everything was good with 2.6.24. After switching to to 2.6.25 I have the following output. cat /proc/cpuinfo from 2.6.25.4: processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 1 model name : Intel(R) Pentium(R) 4 CPU 1.70GHz stepping : 2 cpu MHz : 3450.000 cache size : 256 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 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 pebs bts bogomips : 3402.06 clflush size : 64 scaling_available_frequencies (p4-clockmod): 3450000 5175000 6900000 8625000 10350000 12075000 13800000 The scaling is working but the frequencies are way of. Every value is multiplied by ~8.12. I get the same result with 2.6.25 and 2.6.25.4. I am not sure if this is only a display related problem, or if something more serious is causing this. Please CC me on any replies since I am not subscribed to the list.
