Re: [Bug 132271] Re: [GUTSY] cpu freq scaling not working anymore
I was able to solve my broken ACPI tables by decompiling and fixing the DSDT. The frequency field for the 600 MHz state was 0, hence the line in dmesg: ACPI: Invalid _PSS data: freq is zero I set it to 600, compiled it again and added it to the initrd. Now I can use acpi-cpufreq to scale the cpu clock to either 600 or 1600 MHz (not the full range, but that's enough). It even works in Vista with the DSDT registry override. Keep the good work with Ubuntu! 2008/2/13, Colin King [EMAIL PROTECTED]: ** Changed in: linux (Ubuntu) Assignee: Ubuntu Kernel Team (ubuntu-kernel-team) = Colin King (colin-king) -- [GUTSY] cpu freq scaling not working anymore https://bugs.launchpad.net/bugs/132271 You received this bug notification because you are a direct subscriber of the bug. -- [GUTSY] cpu freq scaling not working anymore https://bugs.launchpad.net/bugs/132271 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 132271] Re: [GUTSY] cpu freq scaling not working anymore
Hi, I'm trying the Hardy Heron LiveCD now. The problem is still the same, Pentium M 1.6 GHz stuck at 1600 and it won't go down. Same problem in Windows, so in my case it is a BIOS bug of the laptop, a Quanta ZW9 (Ahtec X-9600M). I tried this too: [EMAIL PROTECTED]:~$ sudo modprobe speedstep-centrino FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.24-2-generic/kernel/arch/x86/kernel/cpu/cpufreq/speedstep- centrino.ko): No such device [EMAIL PROTECTED]:~$ sudo modprobe speedstep-smi FATAL: Error inserting speedstep_smi (/lib/modules/2.6.24-2-generic/kernel/arch/x86/kernel/cpu/cpufreq/speedstep- smi.ko): No such device [EMAIL PROTECTED]:~$ sudo modprobe speedstep-ich FATAL: Error inserting speedstep_ich (/lib/modules/2.6.24-2-generic/kernel/arch/x86/kernel/cpu/cpufreq/speedstep- ich.ko): No such device [EMAIL PROTECTED]:~$ sudo modprobe acpi-cpufreq FATAL: Error inserting acpi_cpufreq (/lib/modules/2.6.24-2-generic/kernel/arch/x86/kernel/cpu/cpufreq/acpi- cpufreq.ko): No such device [EMAIL PROTECTED]:~$ So I guess the only solution is the phc patch... :( 2008/1/4, Leann Ogasawara [EMAIL PROTECTED]: Hardy Heron Alpha2 was recently released. It contains an updated version of the kernel. You can download and try the new Hardy Heron Alpha2 release from http://cdimage.ubuntu.com/releases/hardy/alpha-2/ . You should be able to then test the new kernel via the LiveCD. If you can, please verify if this bug still exists or not and report back your results. General information regarding the release can also be found here: http://www.ubuntu.com/testing/hardy/alpha2 .

Re: [Bug 132271] Re: [GUTSY] cpu freq scaling not working anymore
I think problem is really important. In windows you can easily fix bad scaling behaviour by using special software. This is not the case in linux. You have to have patched kernel. I thing ubuntu should fix this problem. I'm not sure if this is problem just for few notebooks. Many people could simply miss this bug, not everyone looks at frequency scaling applet for example. I remember, that for very long time many distors supported 2.4 and 2.6 kernels due to changes in new line of kernels. Maybe ubuntu could do the same - keep kernels below 2.6.20 for people with old notebooks? -- .: Leszek Tarkowski :. -- [GUTSY] cpu freq scaling not working anymore https://bugs.launchpad.net/bugs/132271 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 132271] Re: [GUTSY] cpu freq scaling not working anymore
Can you elaborate on how you did this? I've got the same board. On Saturday 27 October 2007 21:30:10 Niels Ganser wrote: I could solve this issue by resetting my BIOS (version 1.08) to optimal defaults on my Uniwill 259IA. So reports of a buggy BIOS causing this seem to be right. However, I think it might still be sensible to hardcode some frequency tables into the kernel as a fallback since many people don't even know what a BIOS is and for those who do, a BIOS update still is a very, very scary thing. -- [GUTSY] cpu freq scaling not working anymore https://bugs.launchpad.net/bugs/132271 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 132271] Re: [GUTSY] cpu freq scaling not working anymore
Yes Dothan cpus may have problems too. Both SONOMA and DOTHAN tables were removed. Looks like there are many computers that experience problem with speed detection though ACPI.

Same here. I would be very interested in a way to lock the cpu at full speed while this is fixed.
