Apparently, there is a known issue with Intel Xeon Processor (Broadwell) E5 v4, E7 v4 and D-1500 processors.  Symptoms include OS crashes with a signature pointing to internal parity errors, PF, DG or UD exceptions.

In my case,  I was using a Cisco UCS B-Series with an Intel Xeon E5-2697 v4 processor...  To resolve this issue, the hardware firmware must be upgraded to 3.1(2b).
