I see it happen too with board designers who choose the wrong jelly-bean
(SSI/MSI) parts for the design. Signals need to be classified according to
criteria including speed, before selecting appropriate components. Too
often I've seen parts used that are known to be problematic when driving
more than a couple of inches, being used to drive long traces with
asynchronous, sub-MHz signals.
