@Anthony Please ignore this kernel option which is added recently and not included in v5.13 release.

@Kent, please check as below and there is only one MEI device on my platform.
root@iotg:/home/seven# lsmod | grep mei

According to your logs, it seems you need 5 MEI devices attached to the board.
