I have a lot of this errors in my Centos stock 4.3 version in an Intel D945gnt motherboard with a Pentium D (dual core)
If I disable apic in the grub.conf (apic=off) will I get a performance hit? Im running Asterisk on that machine.
40 is Received Illegal Vector 20 is Send Illegal Vector 60 means you're getting both errors at the same time.
Basically it means that the APIC bus messages are malformed. The cause can be hardware or software, it's difficult to tell.

Make sure you have the latest BIOS and see if the manufacturer has any linux kernel modules on their site.
APIC should not affect performance, it might affect your ability to auto power off the machine.

Thinking of ACPI? APIC, IIRC, is Advanced Programmable Interrupt Controller. Should have some effect on something?

you turn apic off with a noapic on the kernel boot param line. and you might also want nolapic, the kernel-doc package has more info on what these are and how / when you might to use them.

I really have no idea if that the thing that solved it. I have not changed a thing in my setup but the only thing I did was to update my BIOS firmware with the latest firmware for my intel board (revision 3869) and the problem went away.
I will now leave the machine runnig for a while and see what hppens.

Firmware upgrades quite frequently fix these issues.

I have the following message at boot time:
Local APIC disabled by BIOS -- you can enable it with "lapic"
This might be involved in suspend not working, perhaps or other things. I have the 'latest' bios from HP for my system.
So I found the following message, but after installing the kernel-docs, I cannot figure out which deals with APIC...
