Description of problem: Attempting to use the iscsi-initiator-utils eventually results in the 'iscsid' getting into an uninterruptable sleep. sysrq+t shows that its stuck waiting on a mutex lock. /var/log/messages also has giant lockdep reports about the iscsi code Version-Release number of selected component (if applicable): 2.6.24-0.57.rc3.git4.fc9 How reproducible: Frequent (nearly always) Steps to Reproduce: 1. Install 'iscsi-target-utils' on a server and export a target with a few LUNs 2. On a different machine login to the target, eg iscsiadm -m node -p 10.13.7.47:3260,1 --target pumpkin.virt.boston.redhat.com:storage.virt --login 3. Now logout of the target iscsiadm -m node -p 10.13.7.47:3260,1 --target pumpkin.virt.boston.redhat.com:storage.virt --logout Repeat steps 2 & 3 until one of the commands hangs - usually the --logout command hangs after just 2 iterations The logout appears to have been successful - the client is removed from the active initiators list on the server, and the local /dev/sd* devices have gone away - but the client is hard locked and no further iscsiadm commands work Actual results: iscsiadm logout hangs Expected results: iscsiadm doesn't hang Additional info: Also reproduced on 2.6.23 and 2.6.22 kernels from F7 and F8

This should be fixed in 2.6.25 when it comes out. The patch to fix this is in the scsi maintainer's tree waiting for the next merge window: http://git.kernel.org/?p=linux/kernel/git/jejb/scsi-misc-2.6.git;a=commit;h=9239a5a972d7a2c07e63a7c732801d981109f83d
If at all possible, can this patch be applied to the current Fedora 8 2.6.23 kernels.... I'm working on some projects which use iSCSI and this is a showstopper bug for all development on Fedora 8 currently, and it'll be quite a while before 2.6.25 makes it into Fedora.
(In reply to comment #4) > If at all possible, can this patch be applied to the current Fedora 8 2.6.23 > kernels.... Just the single patch cannot be ported. I can make up a port of all the patches that are in the scsi maintainer's tree. I think we need to ask the FC kernel maintainers what they want me to patch against and if they will take it. Since it is going upstream in 2.6.25 I am thinking they would be ok with it. Do we need to ask Dave Jones or did someone else take over the FC kernel stuff?
Dave Jones is usually the guy, but he hurt himself recently so is taking a few weeks off. The best bet is to start with fedora-kernel-list; the relevant people there should be able to offer some guidance. Chris Lalancette
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. 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 '9'. 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 9'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 9 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 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 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.
