This was primarily in a lighting solution, and it wasn't the only problem with that early hw. We noticed lights not coming back online after a firmware update without a power cycle. Since it was very early hw, IIRC it didn't have any shielding, and also IIRC no pull on TCK.
We now see this primarily on 1st/early iteration hw and on prototypes, but checking this proactively have saved us from a lot of headaches of the type "why doesn't it come back online - hw, or something in the update, or what...".
