Description of problem: Since upgrading my Thinkpad T61p to Fedora 9, there are intermittent periods where the system is unresponsive while (apparently) pdflush/kjournald write to the hard drive (around 1MB/s, as reported by gkrellm). After a few (around 10 to 15) seconds, everything becomes OK again. (Unresponsiveness is not absolute, but for instance it is not possible to select / change the location bar in Firefox). Version-Release number of selected component (if applicable): kernel-2.6.25.3-18.fc9.x86_64 How reproducible: Always, but happens only every once in a while (I haven't found a more precise time pattern yet). Steps to Reproduce: 1. Work normally for a while. 2. After some time, pdflush/kjournald start writing to the disk. 3. Actual results: The system is unresponsive. Expected results: No particular un-responsiveness. Additional info: This did not happen with Fedora 8 on the same machine, as far as I remember. Since I don't really know how to play around with the type of settings involved here, I haven't been able to investigate better the conditions leading to the problem, nor possible workarounds.
After reading about the following problem with Firefox and fsync https://bugzilla.mozilla.org/show_bug.cgi?id=421482 I think this may be what I have observed.
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '9'. 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 9'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 9 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 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
