Seems quite obvious. You shouldn't be stepping through something that handles
serial ports. If you try to do that, data gets flooded onto the serial port
causing an overrun. But if you're getting a problem by just _running_ (not
stepping) the program under GDB, that would be another issue, I guess.

What you could probably do is to run all hardware specific code at one go (use
a breakpoint to do this).
