Description Jan "Yenya" Kasprzak 2009-04-17 13:11:29 EDT
Description of problem: On my laptop (ASUS F3E with the Intel chipset and Core2Duo T8300 CPU), the CPU frequency scaling does not work with the Fedora 10 distribution kernel, the frequency is stuck at maximum (2.4 GHz). With vanilla kernel (at least 2.6.28 to 2.6.30-rc2) I have compiled myself, it works as expected. According to /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver from my own kernel, the scaling driver used is acpi-cpufreq. Version-Release number of selected component (if applicable): All kernels since the F10 release (sorry I did not get time to report this earlier), for example any of the following ones: kernel-188.8.131.52-170.2.24.fc10.x86_64 kernel-184.108.40.206-170.2.35.fc10.x86_64 kernel-220.127.116.11-170.2.56.fc10.x86_64 How reproducible: 100 % Steps to Reproduce: 1. Boot Fedora 10 on an ASUS F3E laptop 2. on an idle system, run "grep MHz /proc/cpuinfo" or 3. run GNOME cpufreq-applet in a desktop session Actual results: The frequency reported is 2.4 GHz, the GNOME applet pops up a window saying "CPU frequency scaling unsupported". Expected results: The idle computer should run at 800 MHz and scale up the frequency as needed. Additional info: I did not found anything interesting when comparing the dmesg(8) output from my own kernel to the distribution one. I am not sure whether the problem was also in F9. This problem may be related to bug #468802.
Comment 1 Chris Parkin 2009-04-27 10:29:03 EDT
Similar problem here on an x48 motherboard with an e8500 cpu. Although I find it works ok on kernel-18.104.22.168-170.2.24.fc10.x86_64 but not on kernel-22.214.171.124-170.2.35.fc10.x86_64 or kernel-126.96.36.199-170.2.56.fc10.x86_64
Comment 2 Jan "Yenya" Kasprzak 2009-06-08 05:54:37 EDT
Still present in 188.8.131.52-167.fc11.x86_64, changing Version: to F10.
Comment 3 Jan "Yenya" Kasprzak 2009-07-01 11:08:30 EDT
Apparently to fix the problem it is sufficient to do modprobe acpi_cpufreq echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor before logging into the GNOME session. So the problem is that the acpi_cpufreq module is not being loaded automatically. My own vanilla kernels have this module built in, and I also select the ondemand governor as a default in my kernel config. I am not sure about a proper fix in Fedora startup scripts, though.
Comment 4 Dave Jones 2009-07-23 10:25:26 EDT
it should be getting loaded by the cpuspeed service, make sure that's enabled. If it is already enabled, can you boot the fedora kernel with cpufreq.debug=7, and attach the dmesg please?
Comment 5 Chris Parkin 2009-07-25 07:48:13 EDT
Created attachment 355140 [details] dmesg output dmesg output for me:
Comment 6 Jan "Yenya" Kasprzak 2009-10-09 04:47:53 EDT
(in reply to comment #4) My cpuspeed service has not been enabled. chkconfig cpuspeed on fixed the problem for me, sorry for the noise. Before closing the bug please wait for Chris Parkin's response whether his problem is the same.
Comment 7 Chris Parkin 2009-10-10 16:58:17 EDT
I cannot start the cpuspeed service. running cpuspeed in a shell fails to start it as well: [root@warpcore ~]# cpuspeed Error: Could not find any CPUFreq controlled CPU cores to manage

(In reply to comment #7) > I cannot start the cpuspeed service. > running cpuspeed in a shell fails to start it as well: > > [root@warpcore ~]# cpuspeed > Error: Could not find any CPUFreq controlled CPU cores to manage Your BIOS is apparently broken and does not support cpufreq: acpi-cpufreq: acpi_cpufreq_cpu_init ACPI Warning (dsobject-0502): Package List length (1D) larger than NumElements count (3), truncated  ACPI Warning (nspredef-0940): \_PR_.CPU0._PSS: Return Package type mismatch at index 2 - found Integer, expected Package  ACPI: Invalid package argument ACPI Exception (processor_perflib-0297): AE_BAD_PARAMETER, Invalid _PSS data  [Firmware Bug]: BIOS needs update for CPU frequency support
Comment 9 Chris Parkin 2009-10-13 16:23:07 EDT
It worked fine under kernel-184.108.40.206-170.2.24.fc10.x86_64 And works fine under Windows But it's not worked under linux since kernel-220.127.116.11-170.2.35.fc10.x86_64 M/B is a LANPARTY DK X48-T2RSB PLUS
Comment 10 Bug Zapper 2010-04-27 09:44:21 EDT
This message is a reminder that Fedora 11 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Comment 11 Bug Zapper 2010-06-28 07:53:04 EDT
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
