Seems like a missed opportunity to try adding a capacitor dead-bug style onto the board to see if it cleans it up.
If it's really 20MHz++ noise that's screwing him, you need something faster than a through hole capacitor IMO to deal with it.
That being said, I'm not 100% convinced this is a 20MHz++ noise issue.
