Hello Folks,

I was just browsing the dmesg on my freshly installed box, and I noticed 
this:

 WARNING: unexpected IO-APIC, please mail
          to linux-smp@vger.kernel.org

The box has a P4 2.40Ghz CPU (model# BX80532PG2400DSL6WF, Supports 
Hyperthreading) on a Gigabyte P4 Titan motherboad (model number 
GA-8IG1000, Intel 865G Chipset)

My # uname -a is below and the dmesg straight after boot is attached, 
let me know if I can send you any more details.
