the kernel is 2.4.3-12 for i686
Comment 2 Arjan van de Ven 2001-09-20 08:33:33 EDT
Does the machine keep functioning? The message in itself is harmless...
Comment 3 acount closed by user 2001-09-20 08:37:18 EDT
The system is very stable and it run ok.
Comment 4 Arjan van de Ven 2001-09-20 08:45:19 EDT
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
