Also affects distribution/package Nominate for series Bug Description Binary package hint: linux-image-2.6.28-6-generic Architecture: AMD64 (EM64T) Kernel Version: 2.6.28-6-generic linux-image-2.6.28-6-generic: Installed: 2.6.28-6.17 Candidate: 2.6.28-6.17 I am using a Conroe C2D (E6750) on an EVGA Nvidia 680i LT reference board, with the latest BIOS update applied. In the BIOS, Speedstep is set to 'Auto' (other option is Disabled), and the processor does report EST capability in its flags. Based on this, I believe I should be able to reduce the CPU speed when system is below full load. However, whenever I attempt to load the acpi-cpufreq module, I get "No such device": $ sudo modprobe acpi-cpufreq FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.28-6-generic/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device Expected Behavior: acpi-cpufreq loads and is able to adjust the CPU speed with the ondemand (or other) governor. Other information: $ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)
