I've tried running kernel-2.6.35-rc3 (x86_64) but the problem persisted. The cpu runs quite hot for a processor of this type: 46-51°C (idle - normal use). Booting with kernel parameter "cpufreq.debug=7" gave the following relevant information in dmesg: acpi-cpufreq: acpi_cpufreq_init acpi-cpufreq: acpi_cpufreq_early_init cpufreq-core: trying to register driver acpi-cpufreq cpufreq-core: adding CPU 0 acpi-cpufreq: acpi_cpufreq_cpu_init cpufreq-core: CPU 0: _PPC is 0 - frequency not limited acpi-cpufreq: No P-States cpufreq-core: initialization failed cpufreq-core: adding CPU 1 acpi-cpufreq: acpi_cpufreq_cpu_init cpufreq-core: CPU 1: _PPC is 0 - frequency not limited acpi-cpufreq: No P-States cpufreq-core: initialization failed cpufreq-core: no CPU initialized for driver acpi-cpufreq cpufreq-core: unregistering CPU 0 cpufreq-core: unregistering CPU 1 cpufreq-core: trying to register driver p4-clockmod cpufreq-core: adding CPU 0 speedstep-lib: x86: 6, model: 17 p4-clockmod: Warning: EST-capable CPU detected. The acpi-cpufreq module offers voltage scaling in addition of frequency scaling. You should use that instead of p4-clockmod, if possible. cpufreq-core: initialization failed cpufreq-core: adding CPU 1 speedstep-lib: x86: 6, model: 17 p4-clockmod: Warning: EST-capable CPU detected. The acpi-cpufreq module offers voltage scaling in addition of frequency scaling. You should use that instead of p4-clockmod, if possible. cpufreq-core: initialization failed cpufreq-core: no CPU initialized for driver p4-clockmod cpufreq-core: unregistering CPU 0 cpufreq-core: unregistering CPU 1 This problem is probably related to https://bugzilla.kernel.org/show_bug.cgi?id=15377 (same cpu, no P-states in powertop).
