Description of problem: with the new kernels 2.6.23.8-63.fc8 and 2.6.23.9-85.fc8 the system seems to hang for 4-5 seconds every 3-4 of minutes. The effect is weird: keyboard input gets repeated (if I'm typing), mouse locks, sound hangs etc, but after some seconds everything comes back to normality. I'm pretty sure it is caused by the kernel because with version 2.6.23.1-49.fc8 this doesn't happen (in fact I still use that version because of this bug) In changelog I noticed this line: * mar nov 13 2007 Chuck Ebbert <cebbert> 2.6.23.1-53 - Disable precise CPU time accounting, fixing a divide-by-zero bug. maybe is this the cause? if you need more informations please tell me how to get them Version-Release number of selected component (if applicable): kernel-2.6.23.8-63.fc8 and kernel-2.6.23.9-85.fc8 How reproducible: always
What kind of hardware? And please attach contents of /var/log/dmesg from working kernel and broken one.

Hello there, sorry for the delay I had to stay away for a while. It looks like those pauses are due to the wireless card. In fact when I disable the wireless networking through Network Manager everything seems fine even on the latest kernels. Even though I'm not sure this depends on the kernel, I attach here the dmesg for both kernels anyway. The hardware is an Acer Aspire 5633WMLi.
this bug is still present in kernel 2.6.23.14-107.fc8 as before if i disable wireless networking everything is fine.
I can verify this problem on a Dell D420 notebook (with running iwl3945 driver). I'm also still running on 2.6.23.1-49 due to those annoying hangs. Any other information needed?
hmm im running iwl3945 too... maybe this happens because of that driver?
this bug is still present in 2.6.23.14-115.fc8

This bug seems to be fixed with kernel kernel-2.6.24.3-50.fc8. My laptop now correctly detects wireless networks without making the system hang from time to time anymore. I still haven't tried to log into a wireless network though. (last not working kernel was kernel-2.6.24.3-34.fc8)
Sorry, on my system those hangs still occur quite often with kernel kernel-2.6.24.3-50.fc8, sometimes they even end up with a kernel panic (very often with 3-34.fc8). Additionally I have problems to connect to a wpa-secured access point. I'm back on ipw3945 now, those hangs exist as well with this old driver but at least I can use wireless over wpa again and no kernel panics occur.
I think, it's not a wireless problem. As those ugly hangs had driven me crazy I tried Fedora9 - no change, no logs. After that I tried Ubuntu "hardy" - same problem but something in the logs: [ 282.382262] psmouse.c: GlidePoint at isa0060/serio1/input0 lost sync at byte 1 [ 282.387778] psmouse.c: GlidePoint at isa0060/serio1/input0 lost sync at byte 4 [ 282.388800] psmouse.c: GlidePoint at isa0060/serio1/input0 lost sync at byte 1 [ 283.499771] psmouse.c: GlidePoint at isa0060/serio1/input0 lost sync at byte 1 [ 283.519122] psmouse.c: GlidePoint at isa0060/serio1/input0 lost sync at byte 5 [ 325.047624] psmouse.c: GlidePoint at isa0060/serio1/input0 lost sync at byte 1 [ 325.048708] psmouse.c: GlidePoint at isa0060/serio1/input0 lost sync at byte 1 [ 325.049797] psmouse.c: GlidePoint at isa0060/serio1/input0 lost sync at byte 1 [ 328.436380] psmouse.c: GlidePoint at isa0060/serio1/input0 - driver resynched. Searching for those messages with Google provided a huge list of problems with a Synaptic touchpad (builtin on a Dell D420). The solution provided were: 1. adding "i8042.nomux" as kernel parameter in grub's menu.lst 2. adding "options psmouse proto=imps" into modprobe.conf This solved my problems. As I don't have Fedora on my notebook anymore, can someone please test whether it fixes the problems there, as well?
This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. 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 '8'. 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 8'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 8 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 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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.
