As this is the first time i see that messages in kerenl logs of FC-12 2.6.32.11-99.fc12.i686. Kindly suggest about these messages, its looking some kernel processing stuck. Thanks Muzi

Hi Any approximate time how it will be resolve, i am facing it again today. Thanks for your reply & comments. Thanks Muzi

Even the mouse cursor won't move. I issued a 'swapoff -a' to workaround that problem. Now it is just individual applications freezing... The applications which freeze seem to be random. Console windows, firefox, thunderbird, konversation, ... Bill
BTW. I see on the ubuntu list a patch kernel patch that resolved this problem for some people, but not everyone...
I forgot to mention I am an running x86_64 kernel. [docbill@hartnell ~]$ uname -a Linux hartnell.local 2.6.32.11-99.fc12.x86_64 #1 SMP Mon Apr 5 19:59:38 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux

Created attachment 427362 [details] dmesg from last kernel crash
(In reply to comment #7) > Created an attachment (id=427362) [details] > dmesg from last kernel crash The exact same thing happens to me too.. and always when I write big files to an nfs share Im running x86_64 Fedora 13, with: 02:00.0 Ethernet controller: Atheros Communications AR8121/AR8113/AR8114 Gigabit or Fast Ethernet (rev b0) I have the proprietary nvidia driver loaded when this happens. $ uname -r 2.6.33.5-124.fc13.x86_64 dmesg of last crash attached above.
I have experienced this on FC-13, also using an NFS share. x86_64 also. This was on kernel 2.6.33.6-147.fc13.x86_64 though I have since updated to 2.6.33.6-147.2.4.fc13.x86_64 Different hardware than above poster, though: 02:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01) 03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 02) Though I have the Atheros, at the time of the lockup the wired connection via the Realtek was in use.

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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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.
Hi, Many people have reported this in Fedora 13, too, which is NOT EOLed.
