+++ This bug was initially created as a clone of Bug #239244 +++ Description of problem: After getting some kernel problems, I finally decided to give kdump a try, but to my surprise, it does not work. Any attempt to use kdump (with sysrq-c or echo c >/proc/sysrq-trigger) leads to instant system crash. sysrq does not work anymore at this point and the only solution is hard poweroff. I see that FC7 does not ship kernel-kdump package anymore, but since FC7 kernel is built with CONFIG_RELOCATABLE, it should be fine as kdump kernel I presume. Version-Release number of selected component (if applicable): kernel-2.6.21-1.3116.fc7 How reproducible: 100% reproducible. Steps to Reproduce: boot kernel with crashkernel=128M@16M option run service kdump start run sysctl kernel.sysrq=1 press sysrq-t or echo c >/proc/sysrq-trigger Additional info: The system is DELL Latitude D620 laptop with Intel Core2 Duo T7200 CPU, 2G RAM, i686 arch. Latest FC7 stuff from development repo. --- Additional comment from green@linuxhacker.ru on 2007-05-14 15:24:47 EDT --- I upgraded to 2.6.21-1.3142.fc7 and the problem is still present. --- Additional comment from fedora-triage-list@redhat.com on 2008-04-03 20:33:50 EDT --- Based on the date this bug was created, it appears to have been reported against rawhide during the development of a Fedora release that is no longer maintained. In order to refocus our efforts as a project we are flagging all of the open bugs for releases which are no longer maintained. If this bug remains in NEEDINFO thirty (30) days from now, we will automatically close it. If you can reproduce this bug in a maintained Fedora version (7, 8, or rawhide), please change this bug to the respective version and change the status to ASSIGNED. (If you're unable to change the bug's version or status, add a comment to the bug and someone will change it for you.) Thanks for your help, and we apologize again that we haven't handled these issues to this point. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp We will be following the process here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this doesn't happen again. --- Additional comment from fedora-triage-list@redhat.com on 2008-05-06 21:41:26 EDT --- This bug has been in NEEDINFO for more than 30 days since feedback was first requested. As a result we are closing it. If you can reproduce this bug in the future against a maintained Fedora version please feel free to reopen it against that version. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp --- Additional comment from matt.castelein@rocsoft.com on 2009-07-24 19:47:31 EDT --- I have encountered this problem on Fedora 11. I am following the instructions at: https://fedoraproject.org/wiki/Kernel/kdump.. When I get to the point where I do "echo c > /proc/sysrq-trigger" the box just freezes and no dump kernel is loaded. It just sits there until I reset it.
The fedoraproject wiki says: How to configure kdump 1. Make sure kernel-kdump, kexec-tools, and crash are installed: yum install kernel-kdump kexec-tools crash ...yet when I do this, I see: No package kernel-kdump available. Nothing to do

This does not work in F12 either. Trigger the crash and the box just hangs. kdump never wakes up to do anything.
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.
