Michael, re:AMD K-2 "yield" flaw

many of the process problems manifest themselves in the form of intermittent failures

This kind of problem is more likely to be a device design flaw rather than anything to do with the process. A common fault is to have a storage bit that gets set and reset at the same moment. The bit gets confused and goes to a one or a zero randomly. The bit works right more often than not when it escapes through the initial checkout procedure. Darn hard to find these at the silicon stage.
