Hi,

The cpufreq list is the right for bugs in this driver.  It's actually
obsolete now, replaced by the acpi driver, but if you're seeing a
message telling you to mail me, you must be using a fairly old version.

Hi, thank you for replying.
You mean the module speedstep-centrino is deprecated now, and I should use acpi_cpufreq on any Pentium M laptop? Even if my kernel is 2.6.17?

No. speedstep centrino is deprated only in 2.6.20 onwards.
2.6.17 acpi-cpufreq or speedstep-centrino any one of them can work for
you
Depending on what your BIOS ACPI support has. So, please try both
acpi-cpufreq
and speedstep_centrino (with SPEEDSTEP_CENTRINO_ACPI enabled in config).
If both of them does not work, please go ahead and open a bug at
bugme.osdl.org
under ACPI related bugs. We can track the issue down systematically that
way.

Also, if none of those two drivers work, it will be interesting to know
whether it is a recent regression or it did not work on this particular
system
with earlier kernels as well.

Thanks,
Venki

I am currently using acpi-cpufreq, which seems to work fine. But I 
thought speedstep-centrino was more specific and suited to Centrino 
processors, that's why I was quite concerned about that failure when 
trying to load the module.
So, just a misunderstanding about those two drivers... sorry!

Thank you,
Federico
