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.
