Description of problem: When on battery power, my notebook's BIOS specifies that the maximum CPU speed should be 1.2 GHz. But immediately after booting on battery, acpi-cpufreq thinks the maximum speed is 2.101 GHz (what it should be on mains power). Switching briefly to mains, or pressing the "power save" button (which imposes a 1.2 GHz limit when on mains), seems to kick it all into place and thereafter the limit is 1.2 GHz on battery, 2.101 on mains. Version-Release number of selected component (if applicable): kernel-2.6.27.10-167.fc10.x86_64 and some earlier. How reproducible: Always. Steps to Reproduce: 1. Cold boot on battery power. 2. Observe CPU will scale up to 2.101 GHz. 3. Briefly switch to mains or press power-save button. 4. Note maximum frequency on battery is now 1.2 GHz. Expected results: Consistent power source--frequency table relationship from boot.
Persists through 2.6.29-0.43.rc2.git1.fc11.x86_64.
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '10'. 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 10'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 10 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
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates.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.
