I'm getting a lot of these messages showing up in dmesg output.
What is a lot? At this point, 314 during my 3 days of uptime.
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
support it)
- Fedora Core 4 for x86_64 with updates as of last week
- kernel-smp-2.6.15-1.1831_FC4 for x86_64
>From http://lkml.org/lkml/2004/4/5/280 I infer that this message means
"Receive Illegal Vector" on the APIC bus.
I would guess that booting with "noapic" would suppress the problem.
I would rather solve it. My machine is new and under warranty (but HP
does not support Linux).
=> if you are running a Athlon X2 CPU, could you check to see whether you are
getting these messages too?
dmesg | grep 'APIC error'
I'd be interested in hearing from you either way. Please describe
your system.
=> The machine came with WinXP MCE. Is there any way I should be able
to observe this problem from WinXP? That would make it easier to ask
for support from HP.
Anecdote:
I used to get APIC errors, years ago, on my Abit BP-6 motherboard running
dual Celeron 300A CPUs. I just put it down to the fact that:
- Celerons were not specifieded to be dual processors (but lots of folks
did run them this way)
- Celerons were on speced to run 50% overclocked (but this was
considered to be Standard Operating Procedure by most folks)
- the BP6 signal runs were not designed as Intel specified for a dual
processor
