[Users] ET release fails 4 tests

Hi,

I reran the "EinsteinToolkitReleased" Jenkins job today, and it has 4 failing tests. The code has not changed since the previous run on 7th October (when all tests passed), but the build and test node is using a different OS and CPU. The change in CPU was unavoidable as the old node is no longer available. The change in OS was somewhat unintentional, but I suspect the problem comes from the CPU. I believe that this was also observed for trunk; is that correct? 3 out of 4 failures are related to NaNs. The 4th is not.
