<br>
Just a heads up that the 3.10.0-862.11.6.el7.x86_64 kernel from RHEL/CentOS <br>
that was released to address the most recent Intel CPU problem "L1TF" seems to <br>
break RDMA (found by a colleague here at Swinburne). The discovery came <br>
about when testing the new kernel on a system running Lustre.<br>

<br>
Stanford have reported it to Red Hat, but the BZ entry is locked due to its <br>
relationship with L1TF.<br>
