[Bug 36014] Re: kernel can't scale cpu frequency

[Fjodor]

I understand that you are fishing for resolution by acpi updates, but I
would like to point out that my /proc/acpi/processor/CPU0/throttling
lists

state count:             8
active state:            T0
states:
   *T0:                  00%
    T1:                  12%
    T2:                  25%
    T3:                  37%
    T4:                  50%
    T5:                  62%
    T6:                  75%
    T7:                  87%

But still:

sune at tommelise:~$ sudo /etc/init.d/powernowd restart
Password:

 * Starting powernowd... /etc/init.d/powernowd: line 83: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: No such file or directory
 * CPU frequency scaling not supported
                                                                         [ ok ]
sune at tommelise:~$

And

sune at tommelise:~$ sudo modprobe speedstep-centrino
FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.17.11-ubuntu1-pentium4m-7/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): No such devicesune at tommelise:~$
