It used to be that shutdown was "instantaneous" (2, 3 seconds or so). So when all of a sudden my shutdown time became 20 seconds I got interested. Why the wait? Questions: What is your shutdown time? According to the system.log from yesterday's shutdown (other shutdowns are similar): Interesting... Illegal instructions, Unknown error code. Why is Spotlight always working at the moment of shutdown? What is happening in the unshown 10 seconds? Any clues out there?
