Consoles
Linux file system image is designed to suit different kernel versions and configurations. Therefore, during the operating system startup, consoles at several serial ports and VGA display are enabled. Some of these devices may not be supported either because of kernel versions incompatibilities or because the kernel was not configured to support these devices. When the console is enabled at such device the following or similar message will appear on active console: INIT: Id "T0" respawning too fast: disabled for 5 minutes This is not an error message, it is just a warning that can be eliminated by editing /etc/inittab file.
