   console_queue_char() may be called from interrupt context
   and waiting for uart to drain the buffer may cause the console to
   freeze. In these situations we should drop the character if
   the buffer is full.
   
   This is an easy solution to this problem, but we should redesign
   console to not do this kind of processing in interrupt context.
