Did you measure directly at the pin of the atmel or do you have any
"preprocessing" ciruit like an amplifier, filter, buffer etc.?

If your input on the pin of the ADC is fine, only two possiblities
remain. You could have a faulty chip or some problem with your software.
I haven't read the datasheet of the atmega32, but I can't imagine any
misconfiguration that would produce random noise on the input. I once
had a problem with the ADC because I didn't wait long enough after
switching channels, so I got data from the wrong channel sometimes,
which produced strange results of course.
