I tried installing Ubuntu Hardy (Kernel 2.6.24) and expirienced the same problems as I did using Suse. So this is not a Suse specific problem. It really seems to me that it is a kernel problem as described by you on lkml, the behavior of my notebook is exactly the same. I started Suse and before starting KDE I went to tty1 and did a cpufreq-info. Then I waitet for some time, and did it again and again. scaling_max_freq was 2GHz the first time (should be 2.5), then 1.2GHz and finally 0.8GHz. That happend within 3 minutes. And now I can not get it back up again, no matter which power-govenor I use. And deinstalling lm_sensors did not help (and it never was installed under Ubuntu and I still have those problems) This really drives me nuts, I mean what's the point in having a 2.5GHz cpu if you can only use 0.8GHz? Is there anything I can do to help solving this problem?

There it "sometimes" happens that freq is limited to 800.

Somthing is using it but I don't know which process. Also I am yet to find a livecd with a kernel that old. If you know one, please tell me. The kernel parameter processor.ignore_ppc=1 did work, I was able to use the maximum frequency. I tested it with SuperPi (http://blog.linuxoss.com/2008/04/09/super-pi-linux-how-fast-is-your-computer...) which gave me a time of 30sec@2.5GHz and 100sec@0.8GHz for 2*10^6 digits of pi. Booting into /bin/bash did also work. I left the system alone for some time to allow it to drop the frequency if it would. The I ran Pi which again gave me a time of 30sec, so I assume the system was at 2.5GHz. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Well, I booted with acpi_osi="!Windows 2006" and now the problem seems to have gone. Great! It's time to move away from osi=Windows ... I already set up a mail for the cpufreq list, but wanted to provide a patch with osi=spec_conform implemented. This is the correct fix (not a workaround) for this machine.

But also in the DSDT we couldn't find anything related to cpufreq so I could be wrong and the missing table might have caused this...

When there is no boot option of acpi_osi!=windows2006, OS will try to load the SSDT table from the address of 0x7F6CDAFC( VIST table). But the VIST table has no signature, which causes that the vista table can't be loaded successfully. As the vist table is not loaded, the _INI will return execption, which causes that the following object can't be executed correctly. Of course the other side effect is that some objects can't be found. For example: \_SB_.PCI0.GFX0.LCD_.BLNF.
Method (\_SB._INI, 0, NotSerialized) { \_SB.OSTP () If (LGreaterEqual (\_SB.OSTP (), 0x40)) { Load (VIST, VSTH) }// because of the error, the _INI object will exit directly. \_SB.FEXT.BINI () // BINI object can't be executed. \_SB.PCI0.LPCB.TINI () //TINI object can't be executed. } From the AML code it seems that the following variables are initialized in the TINI object. > TCDT, TCUT ( the two variables are related with the _PPC object) As the variables related with the _PPC object are not initialized correctly, the cpufreq won't work well. If the boot option of acpi!="windows 2006" is added, the VIST table won't be loaded and the _INI method can be executed correctly. So cpufreq can work well.
After the patch inc omment #32 is applied, the _INI object can be executed correctly and the variables related with _PPC object are also initialized correctly. So in such case the cpufreq can work well even without the option of acpi!="windows 2006". Thanks. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
