>How-To-Repeat:
Image arm64mbr.img.gz onto a micro SD, insert into Raspberry Pi 400 and boot.  Alternatively, this can be reproduced on a regular Raspberry Pi 4 Model B after applying the latest Raspberry Pi 4 EEPROM update available here:

>Fix:
Not provided.  Probably a simply matter of grabbing new firmware blobs from Raspberry Pi.
