APIC and lapic documentation

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...

If I disable apic in the grub.conf (apic=off) will I get a performance
hit? Im running Asterisk on that machine.


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.
