Does the machine keep functioning? The message in itself is harmless...
The system is very stable and it run ok.
Well there is nothing to worry about; "APIC" is an advanced "interrupt controller", and is used mostly for big servers. Linux tries to enable it, but not all systems have one (and you don't need one; laptops try to avoid such components often because they consume energy), and it will fall back to the normal interrupt controller
