Hi,

I booted linux 2.6.26 with cpufreq.debug=3, and it gives the following:

[    0.391292] cpufreq-core: CPU 0: _PPC is 0 - frequency not limited
[    0.391623] ACPI: ACPI0007:00 is registered as cooling_device0

[    8.228001] cpufreq-core: unregistering CPU 1

also cpuinfo attached.

The motherboard is gigabyte GA-G33-DS3R, chipset is Intel G33 ICH9

What can I do to get this working?

Thanks,
Laurence

Hi,

sorry this is a bit unrelated...

Wow, _PPC is evaluated before cpufreq is activated even the initial _PPC call got removed some time ago.
This could be related to the ThinkPads get stuck on lowest freq problem. Ingo Molnar already sent something similar, but did not fully ensure that _PPC is only called after cpufreq has been initialized:
git commit e4233dec749a3519069d9390561b5636a75c7579
I send something to the related bug...

_PPC should not be called before these...

I turned on full ACPI debug, with the _PPC patch, and got this:

The motherboard is gigabyte GA-G33-DS3R, chipset is Intel G33 ICH9

What can I do to get this working?

It turns out the answer was to upgrade the bios, the MB came with version F5, the latest is F7h:
http://www.gigabyte.com.tw/Support/Motherboard/BIOS_Model.aspx?ProductID=2535
which says it's an update for Wolfdale cores...

It's possible to do it from linux userland, which was a pleasant suprise to me, using flashrom from coreboot
( http://www.coreboot.org/Flashrom#Installation ), see also:
http://www.coreboot.org/pipermail/coreboot/2008-July/036747.html

Cheers,
Laurence
