Description of problem: While under heavy IO running Kadischi with Anaconda on a dual processor machine, I get a spinlock lockup on CPU#1 message to the terminal, at which point everything is frozen. Version-Release number of selected component (if applicable): kernel-2.6.21-1.3142.fc7 i686 How reproducible: Randomly. Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info: Screenshot will be provided.
Created attachment 154707 [details] kernel-2.6.21-1.3142.fc7 oops I suspect syslogd is logging actions by Anaconda, and some RPM %post scripts, etc while deploying the package payload for a LiveCD(Kadischi).
Created attachment 154716 [details] kernel-2.6.21-1.3142.fc7 oops Here is some more good stuff from the same kernel, same machine, and same Kadischi/Anaconda LiveCD build happenning. I was able to grab the section out of /var/log/messages.txt before it locked up completely.
The current builds have slab debugging (and other debug options) disabled. There are however kernel-debug packages which are equivalent, with the debugging turned back on available at http://people.redhat.com/davej/kernels/Fedora/fc7/RPMS.kernel/i686/ Whilst further diagnosing this bug, it'd be good if you could run with those instead of the rawhide kernels (there's a .repo file a few dirs up from that url, you can then just yum install kernel-debug)
Created attachment 154787 [details] kernel-debug-2.6.21-1.3149.fc7 /var/log/messages syslogd text It's starting to seem to drop out on me during mksquashfs, while creating a SquashFS filesystem of the LiveCD root filesystem, the SquashFS is also a "parallell" mksquashfs and says it is using both of the processors. In the attached file I have provided output from lspci, lsmod and ps auxw just so you know what the system looks like before any operations are done, except for an initiated Secure Shell connection to the box. If you are not looking for just this message output from /var/log/messages, let me know.
Okay, I give up, where's the doc for decoding the hex dumps?
Created attachment 154975 [details] slab: double free detected in cache 'fs_cache' double free in cache fs_cache This is another syslogd message immediately after invoking an RPM build process with `rpmbuild'.
Jasper, are you still seeing this on the 2.6.23 kernels ? (The messages may have changed slightly since we changed to the slub allocator)
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.
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.
