True, but thank you for the post.

I suspect you are misusing printk and the KERN_XXX prefixes (KERN_DEBUG, KERN_ERR, KERN_INFO, etc.) defined in include/linux/kernel.h. Try dropping the comma between the prefix and the message. That is: printk(KERN_INFO "Hello World!\n"); rather than: printk(KERN_INFO, "Hello World!\n");

I would hate to admit that a typo was "misusing" something, but this was the problem - one of the 35 traces I have in place was mistyped with a comma after the KERN_DEBUG. I think staring at them allowed me to miss this the first four or five times through, and, of course, it was the last one I added - the one that was not supposed to appear at all.
