I also tried building and booting your latest version, but just got "LLC".

I'll try putting a logic analyser on the UART pins to see if anything else
shows up, but I didn't see anything else on the USB-UART at 115200.

Where are the LLC characters coming from? It's a little tricky to grep the
source for a single character :-(
