   Does anybody happen to know how data travels between gpio pins   
   8 and 10 and the system console? In other words, what hardware   
   and maybe software facilitate the exchange? For example, the   
   internal ethernet adapter is connected to the CPU via USB. Is   
   something analogous for the system console?   
      
   I'm seeing what look like console failures on older-model Pi2s   
   (v1.1) and wondering if some accessory subsystem, (usb comes   
   to mind but I don't think that's it specifically) when running   
   FreeBSD-current. The machine stops without complaint or warning,   
   does not answer ping and has to be power cycled.   
      
   Thanks for reading,
