The OS image for the KNL machine has been updated to RHEL7.3 with kernel 3.10.0-514.2.2.el7.x86_64. RHEL7.3 is the first release where RedHat states it has KNL support. OmniPath OPA software has been updated to 10.3.0.0.81. Hopefully these fixes will help with the various recent crashing conditions on these nodes. Let me know what's broken. Ben
