AVR Freaks

I have UART and printf setup "working" on an XMega128A3U with the code below.  I can successfully print text to my terminal, but there are two unexpected results: 1.  The "UART Ready!" text is printed twice, which isn't terrible, but I don't understand why as it is only called once.  2. Instead of printing the integer 13 (or any other number), it prints hundreds of apostrophes (0x60 in hex) for each single call of

printf(" %d ", 13);

Any attempt to use printf for other that text via %u, %i, %f gives similar unexpected results.

The test text line in main loop seems to work fine.

printf("test23456789\n\n");

Relevant code:

void uart_init()
{
	PORTE.OUTSET = PIN7_bm;
	//set transmit pin as output
	PORTE.DIRSET = PIN7_bm;

	//57600
    USARTE1.BAUDCTRLA = (2158 & 0xff) ;
    USARTE1.BAUDCTRLB = ((-6) << USART_BSCALE_gp) | ((2158 >> 8));

	//Disable interrupts
	USARTE1_CTRLA = 0;
	//8 data bits, no parity and 1 stop bit
	USARTE1_CTRLC = USART_CHSIZE_8BIT_gc;
	//Enable transmit
	USARTE1_CTRLB = USART_TXEN_bm;
	}
	
	
	static int uart_putchar (char c, FILE *stream){
	if (c == '\n')
	uart_putchar('\r', stream);

	// Wait for the transmit buffer to be empty
	while ( !( USARTE1.STATUS & USART_DREIF_bm) );

	// Put our character into the transmit buffer
	USARTE1.DATA = c;
	return 0;
}


//inside main:

//init data out uart on PORTE1
uart_init();

//stdio setup
static FILE mystdout = FDEV_SETUP_STREAM (uart_putchar, NULL, _FDEV_SETUP_WRITE);
stdout = &mystdout;
printf("UART Ready!\n");


//Repeated inside Main loop
	printf(" %d ", 13);
	printf("test23456789\n\n");
