My ubuntu 7.10 64bit is working perfectly apart from CPU Frequency scal= ing. This is CPU data: brex@ubuntu-box:~$ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 Duo CPU T7500 @ 2.20GHz stepping : 11 cpu MHz : 2194.736 cache size : 4096 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge=20 mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm syscall=20 nx lm constant_tsc pni monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr lahf_= lm bogomips : 4393.94 clflush size : 64 cache_alignment : 64 address sizes : 36 bits physical, 48 bits virtual power management: (same for Processor 1 - the second core) this is when I try to load acpi-cpufreq brex@ubuntu-box:~$ sudo modprobe acpi-cpufreq =46ATAL: Error inserting acpi_cpufreq=20 (/lib/modules/2.6.22-14-generic/kernel/arch/x86_64/kernel/cpufreq/acpi-= cpufreq.ko):=20 No such device no other modules for frequency scaling work.... I also get this errors about ACPI when loading acpi-cpufreq: [ 1008.017253] ACPI Error (psargs-0355): [\_PR_.CPU0._PSS] Namespace=20 lookup failure, AE_NOT_FOUND [ 1008.017259] ACPI Error (psparse-0551): Method parse/execution failed= =20 [\_PR_.CPU1._PSS] (Node ffff81007cf59de0), AE_NOT_FOUND [ 1008.017293] ACPI Exception (processor_perflib-0234): AE_NOT_FOUND,=20 Evaluating _PSS [20070126] I'm already using latest BIOS for my laptop (F.21...there was a F.13=20 standard when I bought it but I didn't pay attention if speedstep was=20 working on it.) This problem is quite annoying since when CPU runs at 100% for long tim= e=20 I get temps about 70-80=B0C and the laptop gets quite hot. Any suggestion?
