I'm getting a lot of these messages showing up in dmesg output.
APIC error on CPU0: 40(40)
What is a lot? At this point, 314 during my 3 days of uptime.
From http://lkml.org/lkml/2004/4/5/280 I infer that this message means"Receive Illegal Vector" on the APIC bus.
Description of system:
- HP Pavilion a1350n desktop computer
- AMD Athlon(tm) 64 X2 Dual Core Processor 3800+
- ATI chipset
- nVidia 7800GTX PCIe video card (and 450w Antec power supply to
- Fedora Core 4 for x86_64 with updates as of last week
- kernel-smp-2.6.15-1.1831_FC4 for x86_64
I would guess that the APIC bus is mostly internal to the dual core
chip. Not something that the board maker could screw up.
=> if you are running a Athlon X2 CPU, could you check to see whether
getting these messages too?
dmesg | grep 'APIC error'
I'd be interested in hearing from you either way. Please describe
FYI - APIC, ACPI, PCI, PCIe, and PIC are all interlated to Interrupt
assignment / sharing, etc...
(en.wikipedia.org will help define these for you)
Let's see some relevant info about these;
'dmesg | grep -i APIC'
'dmesg | grep -i ACPI'
'dmesg | grep -i PCI'
'dmesg | grep -i PCIe'
Checking for BIOS updates is a great idea to do
Go into the BIOS (with Mobo Manual in Hand and be sure your APIC is
Enabled. and PnP OS is "Yes" also -- if not, try disabling One, then
Both)...could try some Boot cheatcodes 'noapic' apic=off
FYI -- You have a Dual Core AMD64 X2 (2 Cores), not 2 CPUs
Have you installed nvidia's 3D drivers yet ?
