Not sure. I would make sure that your new kernel is the kernel that is being used. We use a different kernel configuration file so that a simple uname command tells us that the right kernel is installed. We use that patch here with 8.3 and it works as advertised. I do wish there was a way to drop the link of the port without kernel mods. Understandably with the out of band management protocols, the internal interfaces really like to keep link alive so you can connect to the system's management console, do wake on lan, etc. -- DaveD
