Tziporet, UNH-IOL completed the testing of the new daily build and here is what we found.
+++++++++++++++++++++++++++++++++++ SL 6.3 2.6.32-279.el6.x86_64 OFED-3.5-20121016-0341.tgz 16-Oct-2012 03:42 18M The new build now allows you to load and unload successfully with no system crashes. We were also able to run the OFA Interop SRP tests successfully. However the Module took a long time (~1-2 minutes) to unload 2. Message saying something to the effect of 'stale connection...retrying' was observed The attached file is a capture from the dmesg output. ++++++++++++++++++++++++++++++++++++ This is bug 2374.
