Version-Release number of selected component (if applicable): iscsi-initiator-utils-6.2.0.871-0.18.fc12.src.rpm (Anything based on 871 series). How reproducible: Unknown. Steps to Reproduce: 1. Configure the iscsi initator util with at least two target devices. 2. Configure it to the maximum amount of logging 3. ????? Actual results: Logging can possibly cause a deadlock in waiting for semaphore access. Expected results: No deadlock to occur. Additional info: This is a backport of the patch from : http://git.kernel.org/?p=linux/kernel/git/mnc/open- iscsi.git;a=commitdiff;h=b95a7ca80b255f0c5b34b2669367b629c8489552;hp=fb4f2d3072bee96606d01e3535c100dc99b8d331 to the 871 series. Mike Christie posted Guy Kerens patch (I think). This patch is already in the EL6 build.
