cpufreq don`t work on centrino CPU in "dapper" (kernel: linux-image-2.6.15-23-686)

I have laptop with centrino CPU..

#cat /proc/cpuinfo

And cpufreq dont`t work on it:
#modprobe speedstep-centrino
FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.15-23-686/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): No such device

I don`t have any meeseges in "dmesg" after this.

[Paul Sladen (sladen)]

 <green-mouse> ok... in ubuntu kernel: modprobe speedstep-centrino
<green-mouse>FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.15-23-686/kernel/arch/i386/kernel/cpu/cpufreq/speedstep-centrino.ko): Invalid module format

Which is giving "invalid module format".

[Matthew Garrett (mjg59)]

If it's giving "invalid module format" and there's no message in dmesg, then the .ko file isn't recognisable as a moduke. My suspicion is that this is due to you getting modules out of sync with locally patched kernels, but it's also possible that it's filesystem corruption.

[Matthew Garrett (mjg59)]

In any case, nothing to do with acpi-support

>Which is giving "invalid module format".

sorry about this mistake... this happan after my games with kernel.

I reinstall linux-image package and now i get this message.

[Bernhard J. M. Grün (bernhard-gruen)]

I have the same processor in my MSI S260 notebook and cpufreq is working. You should reinstall the kernel.
I would say this bug reports is invalid.

I reinstall kernel and cpufreq not work for me...

>I would say this bug reports is invalid.
this is most easy thing to say, If u don`t have time or desire to help...

Gregory: can we check out if you DSDT is broken:

  sudo apt-get install iasl
  cd /tmp
  sudo cat /proc/acpi/dsdt > dsdt.dsl
  iasl -dc dsdt.dsl

and do you get any error messages?

root@green-mouse-laptop:/tmp# cat /proc/acpi/dsdt > dsdt.dsl
root@green-mouse-laptop:/tmp# iasl -dc dsdt.dsl

So does speedstep-centrino now load? If so, what appears in dmesg afterwards?

[Gregory Man (man-gregory-deactivatedaccount)]

no...

Ok, looks like mad hardware. Can you check to see if there's a bios update?

[Gregory Man (man-gregory-deactivatedaccount)]

Yes... I update my bios to last version...

But in my costum kernel all work prefect..
I use linux-source-2.6.15 from dapper + linux-phc-0.2.4 patch (http://linux-phc.sourceforge.net/)

[Gregory Man (man-gregory-deactivatedaccount)]

After analysis of source code of phc pach.
I think problem in ACPI tables, this patch has Built-in Tables for CPUs...

I`am not kernel hacker and this only my suggestion...
