Bug 9753

APIC error on CPU0: 40(40): The APIC received an illegal interrupt vector. The error is detected in the APIC internally. Not much we can do about that.

Is the box working correctly aside of those APIC error messages ?
Are you just worried about the error messages in the syslog ? 

Thanks,

Laptop is working correctly I just emerged KDE and running. But there is one problem when I shutdown it the kernel makes backtrace when it comes to Remounting filesystems. I then tried to boot with noapic nolapic and laptop shutdowns ok. But I don't have the second CPU. I have Core 2 Duo. And one other thing I can hear the disk clicking or something like that. I really don't know how to solve this. I tried with KDE 4 live cd and there are no APIC errors. But with others LiveCD-s the laptop just shutdowns.

I get about 85 APIC errors and also in cat /proc/interrupts ERR in 30 minutes.

Maybe some firmware problems or BIOS problems?

Can you check, whether there is a BIOS update available for your system ?

Thanks,

OK, I booted only with this:

kernel /kernel7 root=/dev/sda5 acpi_osi=Linux noapic

I got to work two cores, but i get lots and lots of interrupt ERRors:

I checked BIOS on acer page there is an update BIOS version 1.21. But for Vista it says.

used libsmbios: getSystemId 
Libsmbios:    0.13.6
Error getting the System ID   : 
Service Tag:  LXAML0X061742258931601
Express Service Code: 9223372036854775807
Product Name: Aspire 7720
BIOS Version: V1.18

I'll try to update it. Hoping for best.

Updating BIOS didn't help.

I have Aspire 5720 and I am featuring this problem also.

Same problem on HPC NX6325.  Anyhow, it dosen't hurt anything, so I just ignore these messages.

i posted this comment in the ubuntu launchpad section asswell
This bug is realy anoying because the loging keeps the disc busy witch is not very nice on a laptop

i know there are several reasons why this bug could be appearing
I happend to get this error to in my log 100's of times. I tried blacklisting my firewire modules as i assumed they were the problem but the are not.

I found out this error only gets printed in my log when my cpu fan is turning and not when it is silent, this error also appears a lot when the fan just starts to rotate.

Hope this might help someone to find a sollution for at least on of these errors

I disabled ACPI for FAN in my kernel 2.6.24 and there are no APIC Error more.

Thanks for solving this wax, thanks again.

i am glad i could help but...
could you please explain how to  dissable acpi for the fan?

Well, actually it turned out that after suspending to RAM, it appeared again APIC error, but then I disabled also ACPI for CPU and now there are no APIC error more, but I can't suspend to RAM.

OK.. I disabled ACPI Fan (and Processor) in kernel like this:

/usr/src/linux -> make menuconfig
Power Management Options -> ACPI( Advanced Configuration and Power Interface) Support -> 
here you have item, Fan and Processor (and submenu after Processor Thermal Zone) I disabled this to, saved config, recompiled kernel.

If you disable Processor in this section also CPU Frequency won't work anymore, because it depends on it.

Miha,
Please download the latest pmtools at:
http://www.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/
and run "./acpidump > acpidump.txt"
and attach the
1. kernel .config
2. full dmesg output
3. acpidump.txt

this is weird, there is no ACPI fan device at all, and there is not difference whether you set CONFIG_ACPI_FAN or not.

Well, the only difference is that if I enable ACPI fan I get about 10000 more APIC error a minute. If it's disabled like now, i get about 100 APIC errors/minute.

Bug is solved over here after upgrading bios to version 1.40 from an acer aspire 7720z. Cpu also runs a lot cooler

Well, Acer finally fixed BIOS. Now there are no APIC at all. Updated to 1.40 version from 1.21

Link: ftp://ftp.work.acer-euro.com/notebook/aspire_7720/vista/Bios
There are many bugs fixed referring to Changelog.

Thanks for help guys.

Thanks for the update. Closing the bug.
