System: AOpen i915GMm-HFS motherboard, kernel 2.6.16 CPU: Intel(R) Pentium(R) M processor 1.86GHz stepping 08 During startup a BogoMips value of 3730.21 is calculated. That should be the correct value for the cpu running at full speed. But: "cat /proc/cpuinfo" on the idle system displays the correct cpu speed, but a wrong bogomips value: cpu MHz : 800.000 bogomips : 3730.21 "cat /proc/cpuinfo" on the busy system displays the correct cpu speed too, but again a wrong bogomips value: cpu MHz : 1867.000 bogomips : 8705.38 The relevant snippets from .config: CONFIG_X86_PC=y CONFIG_MPENTIUMM=y CONFIG_CPU_FREQ=y CONFIG_CPU_FREQ_TABLE=y CONFIG_CPU_FREQ_DEBUG=y CONFIG_CPU_FREQ_STAT=y CONFIG_CPU_FREQ_STAT_DETAILS=y CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y CONFIG_CPU_FREQ_GOV_PERFORMANCE=y CONFIG_CPU_FREQ_GOV_POWERSAVE=y CONFIG_CPU_FREQ_GOV_USERSPACE=y CONFIG_CPU_FREQ_GOV_ONDEMAND=y CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y CONFIG_X86_ACPI_CPUFREQ=y CONFIG_X86_SPEEDSTEP_CENTRINO=y CONFIG_X86_SPEEDSTEP_CENTRINO_ACPI=y cu, knut - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
