   I found some time to rip one out of the installation, solder a cable to   
   the UART pins and boot with a serial console attached.   
      
   I configured /boot/firmware/config.txt:   
      
   ```   
   enable_uart=1   
   uart_2ndstage=1   
   ```   
      
   When I boot with 6.12.48+deb13-rpi it hangs here:
