Normally a user can scroll back with PF7/PF8 if printed messages are outside of the visible screen area. This doesn't work when the kernel crashes, because the scrollback handling is done by the kernel, which is no longer alive after the kernel crash. Add code to always print all dirty lines in the screen buffer, so the user can scroll back with the terminal scrollback keys (Page Up/Down).
