hi!

I found these lines in /var/log/messages. What does it mean? The cpu is a
PIII Speedstep Moblie.

kernel: oprofile: no local P6 APIC. Falling back to RTC mode
kernel: Your CPU does not have a local APIC, e.g. mobile P6. Falling back to
RTC mode

Thanx!

It means that your kernel has correctly detected your CPU type and adjusted
its behaviour accordingly.

... it's information data about system detection. if you want

to learn about APIC, www.google.com:
Searched the web for apic operating system.
Results 1 - 10 of about 13,700. Search took 0.15 seconds.

1. kernel: Ignoring P6 Local APIC Spurious Interrupt Bug...

Hello,

I just re-compilied the kernel(2.0.27) on my redhat4.1 system
with the following hardware:
Dual PPro180(Asus P/I -P65UP5 motherboard)
Adaptec 2940UW SCSI controller
Pioneer 10x CDROM
Quantum XP34500W hard disk
2 Matrox Millenium 4MB cards(one VGA disabled for dual-head)
SB16 sound card, PS/2 mouse and MS keyboard.

I'm getting the following message in /var/log/messages

   kernel: Ignoring P6 Local APIC Spurious Interrupt Bug...

The system runs fine except the Metro-X server freezes up every
so often. I'm wondering if the above might be the culprit.
Just a guess so far.......

Thanks for any info,

-geergev
