Yes, and that has happened more than once. I would reboot and retest code that is crashing, and due to a triple fault, the machine would reboot because of some race, and the little output I get from the console would help tremendously. Remember, debugging the kernel is a lot like forensics, especially when it's from a customer's site. You look at all the evidence that you can get, and sometimes it's just 10 characters in the output that gives you an idea of where things went wrong. I'm really not liking the buffering idea because of this. -- Steve
