Wrong ADC Prescaler Calculation

Wrong ADC Prescaler Calculation in AVR wiring.c

	#elif F_CPU >= 8000000 // 8 MHz / 64 = 125 KHz
		sbi(ADCSRA, ADPS2);
		sbi(ADCSRA, ADPS1);
		cbi(ADCSRA, ADPS0);
	#elif F_CPU >= 4000000 // 4 MHz / 32 = 125 KHz
		sbi(ADCSRA, ADPS2);
		cbi(ADCSRA, ADPS1);
		sbi(ADCSRA, ADPS0);

If F_CPU=7372800 (baudrate crystal)
The prescaler ist set to DIV_32
7372800/32=230400 Hz
230kHz is too much
between 200 and 50 are fine values
