The EC Firmware on an Intel® designed carrier board, chassis element, and assembly element need to be updated to 02.20.00 or later.
The EC Firmware on a custom carrier board needs to reference FW code 1.3.2 or later. Consult with your system manufacturer if you are observing similar symptoms on an Intel® partner product.
