Description of problem: CPU bug reporting mismatch: dmesg reports my i586 CPU has the Pentium F0 0F bug, whilst /proc/cpuinfo says it hasnt. Version-Release number of selected component (if applicable): happens in both kernel-2.6.17-1.2139_FC4 and kernel-2.6.16-1.2115_FC4 How reproducible: boot up with i586 CPU dmesg recognises it has the bug <Intel Pentium with F0 0F bug - workaround enabled> but a look at /proc/cpuinfo after booting and it says there is no F0 0F bug...<f00f_bug: no>. Steps to Reproduce: 1.boot up with an i586 2.look at dmesg for F0 0F bug 3.look at /proc/cpuinfo for F0 0F bug Actual results: Dmesg reports F0 0F bug and reports workaround is applied. /proc/cpuinfo reports no F0 0F bug. Expected results: Expected cpuinfo to say yes for the F0 0F bug, seem to remember it did before. Additional info:

[This comment added as part of a mass-update to all open FC4 kernel bugs] FC4 has now transitioned to the Fedora legacy project, which will continue to release security related updates for the kernel. As this bug is not security related, it is unlikely to be fixed in an update for FC4, and has been migrated to FC5. Please retest with Fedora Core 5. Thank you.
A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable. If you have been affected by this problem please check you only have one version of device-mapper & lvm2 installed. See bug 207474 for further details. If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you.

(this is a mass-close to kernel bugs in NEEDINFO state) As indicated previously there has been no update on the progress of this bug therefore I am closing it as INSUFFICIENT_DATA. Please re-open if the issue still occurs for you and I will try to assist in its resolution. Thank you for taking the time to report the initial bug. If you believe that this bug was closed in error, please feel free to reopen this bug.

This bug is still present as of Fedora 7: kernel 2.6.23.8-34.fc7 Cannot verify against Fedora 8 as I sadly can't get it to install. Cheers.

This message is a reminder that Fedora 7 is nearing the end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 7. 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 '7'. 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 7'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 7 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. 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. If possible, it is recommended that you try the newest available Fedora distribution to see if your bug still exists. Please read the Release Notes for the newest Fedora distribution to make sure it will meet your needs: http://docs.fedoraproject.org/release-notes/ The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Update distro tag to FC8 due to butt-triage infantility.
