Hope i'm right in this place, thanks in advance, thomas ps: 1. from dmesg: CPU: Intel(R) Pentium(R) III Mobile CPU 1000MHz stepping 01 2. from /var/log/messages: cpufreqd: parse_config_general(): ACPI workaround enabled. 3. using debian-kernel-source-package (kernel-source-2.6.6) with following part-.config: (the same behaviour was with kernel-source-2.6.5) --- # CPU Frequency scaling # CONFIG_CPU_FREQ=y # CONFIG_CPU_FREQ_PROC_INTF is not set # CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE=y CONFIG_CPU_FREQ_GOV_PERFORMANCE=m CONFIG_CPU_FREQ_GOV_POWERSAVE=m CONFIG_CPU_FREQ_GOV_USERSPACE=y # CONFIG_CPU_FREQ_24_API is not set CONFIG_CPU_FREQ_TABLE=y # # CPUFreq processor drivers # # CONFIG_X86_ACPI_CPUFREQ is not set # CONFIG_X86_POWERNOW_K6 is not set # CONFIG_X86_POWERNOW_K7 is not set # CONFIG_X86_POWERNOW_K8 is not set # CONFIG_X86_GX_SUSPMOD is not set # CONFIG_X86_SPEEDSTEP_CENTRINO is not set CONFIG_X86_SPEEDSTEP_ICH=m CONFIG_X86_SPEEDSTEP_SMI=m # CONFIG_X86_P4_CLOCKMOD is not set CONFIG_X86_SPEEDSTEP_LIB=m # CONFIG_X86_SPEEDSTEP_RELAXED_CAP_CHECK is not set # CONFIG_X86_LONGRUN is not set # CONFIG_X86_LONGHAUL is not set --- -- ____________________________________________ Thomas Breitner mail@tombreit.de | http://www.tombreit.de
