Customers do not see error counts.  I do not think it's bogus.

This model is basically the same as your car.  You do not see error
counts or periodical normal errors from all kinds of controllers in the
car while you are driving.  You get an attention lamp lit when you need
to bring it to a car dealer.

We've been providing this model for many years now.  I am just trying
to enable OS error reporting with ghes_edac.
