It's not a bug...it's life. The message buffer has to be limited, or it
opens the kernel up to DoS attacks if the buffer can grow without limit
and consume all memory. It might be nice if the buffer size were made
tunable so that on big systems, you can see all the bootup messages before
the buffer fills.
