Description Beth Uptagrafft 2017-10-18 15:59:40 UTC
Potential customer seeing a kernel panic when they bring an Intel Omnipath communication fabric into the mix using kernel-rt-3.10.0-693.2.1.rt56.620.el7.   RHEL+RT good.  RHEL+Omni-Path good.  RHEL+RT+Omni-Path bad.  

Clark reproduced the problem internally.  He grabbed the test kernel built for a hfi1 issue in bz#1383737 and it is booting successfully. Doing additional testing to verify Omnipath functionality.
