[Asterisk-Users] APIC error on CPU0: 60(60) and asterisk crashes

[Erick Perez]

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) and kernel
2.6.9-34.ELsmp

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.
