I am not sure but try and change it anyway. > Would moving the cards impact this (the problem, not the interrupts)? This is always good to try. > Indications of a bad board? Maybe because it only happens on the first tuner and not the second. The best way to make sure the card is not bad is to try it under windows. So if it also does not work in windows you are sure the card is bad.
