Description of problem: Upgraded laptop from F8 to F9. There were problems with X-Windows associated with Bug #430416 [XFS problems]. Gnome now seems to be functional after disabling XFS, but with an extremely high CPU overhead on Gnome-Panel. Gnome-System-Monitor report CPU usage at around 60-97% utilisation [not good]. There is no HD activity associated with this bug. Version-Release number of selected component (if applicable): GNOME gnome-panel 2.22.1.3 Gnome desktop version: 2.22.1 Linux 2.6.25.3-18.fc9.i686 How reproducible: Stopped and started Gnome / Xwindows three times so far...this is not a freak occurrence. Steps to Reproduce: 1. Start up computer 2. Gnome starts up 3. Top / Gnome-system-monitor shows high CPU utilisation Actual results: Gnome desktop is currently running slower than F8 Gnome desktop. Expected results: Gnome should be sitting quietly and not eating up CPU cycles for no obvious reason - whilst there are no programs running. Additional info:
Created attachment 306365 [details] output from top
more useful than top would be the output of strace on the panel process when it does this.
Wilko - I managed to temporarily fix the problem when I killed the process. The process then restarted and has been working normally since. I'll keep this open for a week, and then close it if nothing has been progressed.
I'm seeing the exact same behaviour. I just updated to F9 and now X is not working.

Sorry I ain't going to do debuginfo-install - it probably will pull in a few GB of debug info packages... :-(.

You could control-c out of the install after it tells you how much it really needs to download ;-) Can you think of the process that led up to the issue ? Had your machine been up and logged on for a long time ? Have you been able to reproduce the symptoms again ? Would updates have been installed during the machines runtime, perhaps a gtk or glib update ? {It hasn't happened to me again, so I don't have any further info to add}.
It happened once so far; my machine crashed on suspend (known issue and due to lack of swap space), and on restart, some of the gnome session data is broken and the workspace icon at the bottom left shows only 1 workspace (again a familiar issue after a crash), so I do ctrl-alt-backspace to restart the X-server (this tends to cure the corrupted work-space issue), and that's when it happened. So it could be a side effect of the crash or even the ctrl-alt-backspace. I am pretty sure the debuginfo-install will pull in glibc, gcc, and the bulk of gnome, so it is going to be hugh :-).
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.
