The errata is supposed to be
here, but it is not.
You need to submit a service request to get the errata.
Also submit a service request about the problem.
You will need to dialog with service to clarify it, but they are EE's, so they will understand what you are saying.
I am sure you tried this, but if you change out the xtal, does that help?
For now, I would save the bad boards and if the service request does not resolve the problem, you should tell them you want to send a board to engineering.
