Description of problem: After the update from the release kernel (2.6.31.5-127), the fan suddenly started turning loudly (really very loudly that i have to shutoff the laptop ) and then stops all of a sudden. I believe that this happened between kernel-2.6.31.5 and kernel-2.6.31.6 Version-Release number of selected component (if applicable): >2.6.31.5-127 How reproducible: I can't reproduce it till now, but i have it on 2.6.32 too
I have the same problem on a Toshiba laptop with a Core 2 Duo CPU and Intel graphics. The problem started around the same kernel version. Whenever the CPU is under load (e.g. restoring a browser session that crashed, so it has to open lots of tabs), the mouse gets really jumpy, and if it locks up for long enough then the whole system freezes and the fan goes nuts about five seconds later. I have to run a Fedora-12 kernel on this Rawhide system just to make my machine usable. (I have another desktop system with a quad Opteron CPU and nVidia graphics, also on Rawhide, and the mouse is not even jumpy on that machine.) I don't know if it's the KMS part of the Intel graphics driver or the kernel scheduler causing this problem, but for me right now Fedora 13 is unusable with the 2.6.32 or 2.6.33 kernel, because my machine will lock up hard within five minutes of use every time I boot it.

I still get hard kernel lockups with a fresh reinstall of Fedora 13 Beta with all updates applied. Kernel version is kernel-2.6.33.2-57.fc13.x86_64. Lockups are a bit harder to trigger since kernel-2.6.33.1 or so, but if I leave my computer on overnight it's always locked-up in the morning, and it still frequently locks up under load. I have to run kernel-2.6.31.5 or earlier on my machine just to avoid lockups. Please can somebody look into this bug before Fedora 13 is released? What info do you need to debug this?
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '12'. 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 12'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 12 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 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 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.
