Matrix CPU: Why this message scrolls on the CPU display : "EQUE/IVC32/LMC64 FPGA Version Usupported"

If you did an upgrade on the cards, most likely one of the cards didn't upgrade properly, or failed, and the system doesn't recognize the version.  Run a FirmWare report and identify the card(s).  Either upgrade the card again, following the appropriate process or remove it from the frame.  This should stop the scrolling message.
