Firmware/Keyboard Failure on ANSI PBP

[bcnaz]

I had a complete freeze and failure on ANSI PBP while running a Debian dist-upgrade (Bullseye).
The system now boots to login, including with stock MrFixit, but there's no keyboard or trackpad input of any kind - this includes USB KB inserted any stage, prior to or after boot.

I've tried different SD, eMMC, and disconnecting nvme. This occurred with a modified image, but KB problems are present on stock image from SD and original u-boot.

One of my eMMC images was quick enough with original uBoot, to allow me a capture of multiple firmware load failures - however I'm at a loss as to spotting what might be incidental and what is catastrophic:

Anyone with suggestions or know-how? Help is welcome.

Could this possibly be related to the "spill" you posted about previously  ?

Replacement keyboards will hopefully be available soon
