The kernel occasionally sends messages to your screen. The
following is a list of some of these messages and what they mean.
Frequently, these messages indicate something is wrong. Some of these
messages are critical, which means the operating system (and all
your programs!) stops working. When these messages occur, you should
write them down and what you where doing at the time, and send them to
Linus. See Section .
Luckily, some of these messages are merely informational---hopefully, you'll see them more often!
