- after the update to kernel-2.6.24.5-85.fc8 even the kernel-2.6.24.4-64.fc8 lost its ability to run cpuspeed (with kernel-headers-2.6.24.5-85.fc8) please boot with cpufreq.debug=7 and attach the output of dmesg. Created attachment 304228 [details]
dmseg output
dmseg created with cpufreq.debug=7 option
dmseg says: speedstep-lib: x86: 6, model: f speedstep-ich: Intel(R) SpeedStep(TM) capable processor not found speedstep-lib: x86: 6, model: f speedstep-smi: No supported Intel CPU detected. but model : 15 model name : Intel(R) Core(TM)2 CPU 6320 @ 1.86GHz stepping : 6 actually IS SpeedStep(TM) capable! That 'not found' message is expected. There are 3 different variants of speedstep, and that message comes from the driver for the pentium-III era version of speedstep. Your CPU should be using acpi-cpufreq, but for some reason it looks like that isn't getting loaded. Can you try modprobe acpi-cpufreq from the command line, and see what that does ? Also, the output of /proc/cpuinfo might be handy. $ modprobe acpi-cpufreq FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.24.5-85.fc8/kernel/arch/x86/kernel/cpu/cpufreq/acpi-cpufreq.ko): No such device CPU1 cpuinfo (CPU0 dupl.): processor : 1 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 CPU 6320 @ 1.86GHz stepping : 6 cpu MHz : 1866.712 cache size : 4096 KB physical id : 0 siblings : 2 core id : 1 cpu cores : 2 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_lm bogomips : 3733.35 clflush size : 64 ok, you have the est flag, so all should be good. It looks like the BIOS for some reason has broken P state tables. Can you attach /proc/acpi/dsdt please ? Also, you may want to make sure you're running the latest version of your BIOS if there are updates available. I have encountered some problems with BIOS already (freezing, BIOS CRC checksum error). I'll try re-flashing it. Created attachment 304249 [details]

Dave, thanks for your help and sorry for wasting your time! The BIOS updating solves the issue. Now the cpuspeed is working again. (However the "speedstep-ich: Intel(R) SpeedStep(TM) capable processor not found" message is still present) You can close this bug. Have a nice day and thanks again Radek |
