I have attached an output of "sudo lspci -vv".
All of this ws captured without the broadcom (bcm43xx) module loaded.

I have attached the dmesg log captured soon after a bootup.
I am using a fixed DSDT for the Ferrari 4005 (which I fixed myself).

[NOTE: While looking over the log file it eventually filled up the dmesg buffer, but I noticed the "many lost ticks" warning at the end]

same here for me after edgy final on my acer ferrari 4005. not sure what apic does, but maybe that's why my wireless networking, battery status, and 3D acceleration all are broken in edgy whereas they were working in dapper. makes edgy unusable at the moment. :(

I managed to reduce (but not completely solve) this by appending some kernel command line params which I've details here:
  https://launchpad.net/distros/ubuntu/+bug/69026

I've found the cause of these errors on my machine.

All I need to do is remove the ohci1394 module ie:
  sudo modprobe -r ohci1394
and the messages immediately go away.

I haven't yet found a way to disable this module on bootup (blacklisting it doesn't prevent it from loading).

So it appears to be a firewire issue?
Ben Collins works on the Linux1394 project, perhaps he knows of the cause and correct fix?

Manuel/Ralf: Does this remove your error messages as well?

I guess it's explicitly loaded by dbug or discover...

I'm trying this out as we speak. Last message I'm seeing is the module
removal message.

Removal seems to work for me.

Same problem on my Acer Ferrari 4005 since upgrading to Edgy , with a custom 2.6.18 kernel.

I've tried removing the ochi1394 as suggested by Ralf but that does not resolve the peoblem for me. I still see frequent APIC errors, although they seem to be reduced (slightly) since removing the ohci module.

Update BIOS?

The update bios comment is really helpful.
(note the irony here!)
How do I update the BIOS WITHOUT (!) having to install Windows?

Disregard my last comment. I created a bootcd from FreeDOS and was able to perform a BIOS upgrade. Let's see how it goes!

Please retest against 2.6.20-2 when it is available in the feisty archive.

with me it didn't help
same messages appears
is there any information i can provide

output of dmesg

Yeah, tell me if the BIOS update worked. Seems it did for others. Seems it did for others.

Pliss close report, not is problem of Ubuntu. It is problem of vendedor of hardware. Update BIOS and not problem.

Not is problem of Ubuntu (Kernel). It is problem of BIOS. Update BIOS and not problem.

there was a similar problem with Dapper where updating the BIOS fixed it, but this is not it. as Jani reported above and i can confirm, this problem is still there running with fully updated BIOS. i'm not an expert at these things, but it looks like Edgy simply does not handle interrupts properly on these systems.

Adding myself to the list as I see the same problem on a Toshiba Tecra A8:

Not sure whether it is the same issue but at least the phenomenon is the same (log file filling up with "APIC error on CPUx"). Seems to start only if the system is put to some load, though (launching Eclipse, VMWare or a database server).

Removing the ohci1394 module doesn't help, either:

I don't know whether this is really causing any trouble or just being an "aesthetic" thing, but I would like to have getting it fixed anyhow. Kernel is 2.6.17-10-generic from Edgy.

Thanks,
Kristian

i haven't checked feisty yet. can anyone confirm?

I'm willing to add my experience as to whether the BIOS update fixes the problem, but I need to get a bootable DOS medium in order to flash the BIOS. I've had no luck so far getting my USB key to boot into FreeDOS and I don't have a floppy drive available. As soon as I figure it out I'll post the results back here.

I've got the same errors on my Asus L5800C laptop. Even worse: i've had no problems running breezy and dapper but I am since recently experiencing random hangups in Edgy.

This results in the keyboards (1 onboard, 1 ps/2 through usb) not responding (mouse and touchpad still do). Then either no program in gnome starts anymore or when I can make it reboot it hangs on errors from the bcm43xx Broadcom wifi driver. I have to do a hard reset and then at boot when I have to enter my boot password set in the bios only the laptop keyboard works, the external one does not until linux boots.

Just did a completely clean install of Edgy yesterday and this still seems to occur. Sometimes nothing happens for two days straight and sometimes it hangs three times in one day.

I hope these data will help:

Ben, Cristian: As Alvin pointed out above, updating the BIOS on Acer Ferrari 4005 WLMi does not solve this problem. I just updated from BIOS 3A19 to 3A23 and still have as many of these messages in my dmesg output. Upgrading the BIOS is not the answer.

However, the BIOS update coupled with the irqpoll kernel option at boot does appear to have stopped the APIC error messages.

Output of dmesg with irqpoll option after upgrading BIOS to 3A23.

Output of lspci -vv with irqpoll after BIOS update to 3A23.

I seem to be getting the same - on my Toshiba M500.
Had installed edgy 4 days ago and things were fine. Since yesterday, machine has been behaving slowly - apps coming up after sometime. Today morning the boot process stopped twice at the same point (after local mounting of drives). However, if I resort to safe boot - and then "do nothing" and an exit, the xserver comes up fine (though app launch times are quite large)

Checked logs and saw a lot of the APIC error messages showing up. Then chanced on this thread.

Any inputs required, pls update and will mail in the same.

I have recently upgraded to Feisty (linux-image-2.6.20-9-generic) and the frequency of these messages is greatly reduced, although they are not eliminated completely. I intend to take a look at the Linux Firmware Kit suggested by Cristian above, but something has clearly changed in the kernel that has at least reduced the severity of the problem.

I note that when I boot, I see the message "MP-BIOS bug: 8254 timer not connected to IO-APIC" before the usplash screen. See attached dmesg output.

I have submitted a Linux Firmware Kit report for the Acer Ferrari 4005 WLMi with BIOS 3A23. It is currently awaiting moderator approval, but should be available via the archives at http://www.bughost.org/pipermail/firmwarekit-results/ soon.

removing myself from the list. For the Tecra A8, a new BIOS (3.30) has been released in early 2007 which seems to have fixed the problem.

Thanks anyhow. :)

This really looks like a hw/BIOS bug. Please re-open if that proves to not be the case.

I experienced the same problem (only installed ubuntu Edgy Eft a day ago)
prj@gordon:~$ grep "APIC error" /var/log/* | wc -l
335551

Tried updating to latest known BIOS version (1.04c AMI) for Fujitsu-Siemens Amilo 7640W didn't help. Neither did adding boot options noapic (then sound device died and Gnome wouldn't come up) nor nolapic (same thing) or trying to set various i8042 boot options. What seems to have cured it is setting the boot option irqpoll (add it in /boot/group/menu.lst on line beginning with kernel). Not trying to reopen the issue, just adding a comment with workaround that might help others with same problem. This discussion was first hit on google when I searched for the problem. I spent lots of time reading forum posts all over the net about this. Maybe there is no general solution, and it's not really a BIOS problem (at least not only, though it might be for some) and all those "solutions" are workarounds for linux kernel not to alert about faulty hardware. Well, those are my 5 cents. Thanks for good work on making Ubuntu.

As a newbie with the same error, could you give me a specific line entry for 'irqpoll' I'm not quite sure how to enter it and don't want to muck things up. Thanks

Certainly. When you first boot, before the Ubuntu splash/progress screen, GRUB should present you with a list of options. The first should be something along the lines of "Ubuntu, kernel 2.6.20-15-generic Default" (I believe it will be 2.6.17 for Edgy).

Press 'e' to edit the boot configuration. You should see a list of options like the kernel, root device, initrd image. Use the cursor keys to select the kernel line.

Press 'e' to edit the boot options. You should be presented with the current boot options, something along the lines of "/boot/vmlinuz root=UUID=e9c019e5-d78a-4cc0-8c4a-129eadbe0e3b ro quiet splash" although the line is so long it will probably have been wrapped so you will only see the latter part of it. Simply add " irqpoll" (note the leading space) to this line, then hit enter.

You should be taken back to the boot configuration screen. Press 'b' to boot.

You can make the option permanent, if you so wish, by editing /boot/grub/menu.lst and adding it to the line "# kopt=root=UUID=e9c019e5-d78a-4cc0-8c4a-129eadbe0e3b ro" in the "Default kernel options" section, then running "sudo update-grub"

Hi James,

Sorry for the delay in reply. I have followed your advice and made a
permanent change to my grub. The APIC error message has now
disappeared. Thank you. Maurice

I use Ubuntu 6.10...
ubuntu - linux for human beings <http://www.ubuntu.com>

same bug is resolved on Toshiba
Details at
https://launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/84204

I use a HP dv8000 laptop with AMD Turion ML-37 processor. I have had this error in both Edgy and Feisty..Fesity as an upgrade and as a clean install. I will add the irqpoll option and report back results

Had tried based on the May 9th feedback

a) irqpoll did not help
b) looked at updated 3.5 version bios - that sorted out the issue.
However, now during direct boot, I do not get the grub selection menu. (But it is manageable - by instinctively selecting the first or last option in my dual boot)

Interestingly, if I do a reboot (instead of shutdown), the grub options come up fine.

I added irqpoll by itself, then irqpoll with noapic, then irqpoll with nolapic. irqpoll by itself did not affect any changes. adding it with nopaic caused system stop at very beginning of boot process. Same thing with nolapic, but a different error. I am researching flashing the BIOS att. Report back when I figure that out.

BIOS upgrade on Toshiba Tecra A8-183 to version 3.40 fixes this issue.

Try recompiling the kernel without IDE support. Use the pata_sis module and /dev/sda instead. You will have to redo grub and initrd.

This got rid of the APIC error on CPU0: 40(40) on a SiS 755 chipset + Athlon64 using 2.6.22-rc6-git2 kernel. The motherboard board is a Foxconn K8S755A-6EKRS.

Problem started occurring for me when upgrading edgy server to latest kernel (2.6.17-12-server).
No errors before upgrade, even with 296 day uptime.

Within 1 day of uptime, here is the output:

My BIOS is up to date as well. On my Acer Aspire 3004WCLi, I have version 3A32 - the latest (and probably the last) bios release.

Hi Nanley,

Since it appears you are running the latest Hardy Alpha release, per the kernel team's bug policy, can you please attach the following information. Please be sure to attach each file as a separate attachment.

* uname -a > uname-a.log
* cat /proc/version_signature > version.log
* dmesg > dmesg.log
* sudo lspci -vvnn > lspci-vvnn.log

For more information regarding the kernel team bug policy, please refer to https://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks again and we appreciate your help and feedback.

The files you've requested...
By the way, adding the noapic option to grub stops this error from occurring. Would anyone know, by any chance, what this option does - or what it stops the OS from doing? Thank you.

Adding the noapic option has caused some errors. My cd drive will not operate, and running software like brasero crashes.

The guys on http://bugzilla.kernel.org say that this message is just a symptom, not necessarily the same bug. I have this message too and I don't think it is connected with any abnormal activity. If your system works fine then you should just ignore it. If not, you can search the kernel's bugzilla for a bug that is most probably connected to your hardware.

There is an interesting comment in Bug #69026:
"I must remove the "ohci1394" module or dmesg gets constantly flooded with APIC error on CPU0: 40(40)"
Maybe this will solve the problem for some of us? (especially if you don't use firewire - if you do, then don't remove that module)

It freezes pc after a few of the APIC errors.

Well, my system seems to work normally when I ignore the errors, but I can't help but think there is some "polling" going on that is wasting resources. Here are my boot logs (normal, and noapic).

i know there are several reasons why this bug could be apearing
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 apears a lot when the fan just starts to rotate.

I have an acer aspire 7720z (not with latest bios but that wil be installed this weekend and that might solve the error)
Hope this might help someone to find a sollution for at least on of these errors

i recently installed ubuntu 64 bit on my acer. With 32 bit it gives die apic error, with the 64 bit it does not. I hope it stayes this way :D
Also the fan seems to be more quiet

don't mind my previous 64 bit comment. in stead of the apic 40 error i get this.

not the same, but i similiar problem here https://bugs.launchpad.net/ubuntu/+source/linux/+bug/188739

I upgraded my bios yesterday (from version 1.22 to 1.40)and got rid of the" CPU1: Temperature/speed normal message" in 64 bit mode. I asume this is the apic(40) error in 32 bit mode.
My cpu is now running a lot cooler.

So the people with acer asprire 7720 might fix this with a bios upgrade

For the bug triagers.....if you wish to mark this bug as invalid, please give us the courtesy of explaining your rationale.

Larry,

It appears as one of the remote bug trackers marked part of the bug as invalid... The remote bug trackers watch upstream bug reports and update launchpad appropriately, chances are an explanation was given upstream.

------- Comment #19 From Miha 2008-06-14 09:50:15 [reply] -------

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.

------- Comment #20 From Natalie Protasevich 2008-06-14 20:50:28 [reply] -------

Thanks for the update. Closing the bug.

And for those of us experiencing this on a machine other than an Acer Aspire 7720? I note that Acer appear to have a new BIOS available for the Ferrari 4005WLMi (version 3A27 I think, see ftp://ftp.work.acer-euro.com/notebook/ferrari_4000/vista/BIOS/BIOS.zip) but it is labelled as "Bios for MS Windows Vista". This seems to tally with Richard Seguin's link above, but can anyone verify my assumption that this BIOS will be safe to use with Ubuntu?

i must misunderstand something here......

what about the rest of the world not using Acer?

the bug fix is to change machine and update BIOS?

Ralf, since you are the original reporter is this issue fixed for you?

As for the rest of you experiencing this same problem I understand that it is still very frustrating for you and it would be helpful if we could fix your APIC issues as well. It appears as this bug was hardware specific and as a result I am asking whoever else is having this problem to please submit a separate bug report (** and please indicate what your hardware is **) so we can move forward with this issue.

Thank you,

Richard Seguin

What is the fix? Is it supposedly fixed in a recent kernel?
I haven't seen the error in a while :)

This is where this bug gets confusing, there are few people here with the same symptoms... The original fix was a bios upgrade...

What kernel are you running now? and just to confirm your not having this problem anymore?

mp,

Unless you have exactly the same hardware as Ralf could you please submit a separate bug report for your hardware.

Thanks,

$ uname -a
Linux acerbus 2.6.24-18-generic #1 SMP Wed May 28 19:28:38 UTC 2008 x86_64 GNU/Linux

$ dmesg |grep -i apic
$

So it's gone for me.

Good enough. Closing this issue out as it was hardware specific and the original reporter is no longer having the problem. If you are still experiencing this problem please refile a new bug report.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.
