*** Bug 558230 has been marked as a duplicate of this bug. *** Looks like this upstream commit is causing some false positives: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=846f99749ab68bbc7f75c74fec305de675b1a1bf The fix is here: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux-2.6.git;a=commitdiff_plain;h=6992f5334995af474c2b58d010d08bc597f0f2fe I don't think this needs to be a blocker bug. Thanks for the feedback Chuck. Agreed at the F13Blocker meeting to move this issue to F13Target (nice to have) since this doesn't prevent RAID installations and you've already identified the upstream false positives that might be triggering this. This may be added to Common_F13_Bugs later should more reports surface. FYI, seeing this with F-13-Final-TC1. I know this isn't supposed to be fixed. There was some discussion during blocker meetings that the 'possible circular locking dep' messages would go away when debugging was disabled in the kernel. Just posting here so folks know these messages still appear. ======================================================= │ [ INFO: possible circular locking dependency detected ] │ 2.6.33.2-57.fc13.x86_64 #1────────────────────────────────────────┘ ------------------------------------------------------- mdadm/1042 is trying to acquire lock: (&bdev->bd_mutex){+.+.+.}, at: [<ffffffff81147072>] __blkdev_get+0x91/0x3a8 Removing from CommonBugs since these messages no longer appear with F-13-RC3 This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '13'. 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 13'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 13 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 13 changed to end-of-life (EOL) status on 2011-06-25. Fedora 13 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. |
