I noticed this message in my system logs after replacing the motherboard.
"An unexpected IO-APIC was found. If this kernel release is less than
three months old please report this to linux-smp@xxxxxxxxxxxxxxx"
The MB is an ASUS P4S533-MX, quite old, early 2003.
Attached is a complete dmesg for kernel 2.4.36.9
Duane.
