Bug Description

Binary package hint: ubuntu-base

Applies both to Ubuntu 8.04.1, Kernel 2.6.24-19 server and Ubuntu 8.04.1 Kernel 2.6.24-19 generic (desktop).
Both in the server and generic desktop versions of the OS installed on the same machine, an Intel D945GCLF MB w/ Atom CPU. Makes no difference if hyperthreading is enabled or disabled except that when it is disabled, I can't do anything more after the CPU is locked up. In both versions of the OS, I thought that the problem might be CPU temp related, but now I am sure that it is not. Rather, it seems like it is CPU activity related -- even if the CPU is cool, the problem is correlated with a lot of CPU activity. It is not related to a particular application that I'm running. When using the system monitor in the desktop version, I can see CPU #1 going into the lock-up mode, but apparently CPU #0 does the update of the system monitor. No process is shown with high CPU activity. For both versions of the OS, it is impossible to shut down the computer using the OS. The busy CPU prevents all of the processes from terminating. Under the desktop version, once CPU #1 gets locked up, it is possible to undertake one more step in Gnome, at which point it locks up. The locked/busy CPU never becomes unlocked/unbusy.

No problems running Win2k on this computer.

From my Google searches, I have noted that quite a number of different CPU's, motherboards, and versions of Linux (not only Debian derivatives) are suffering from this problem, and it manifests itself under a wide range of circumstances. Smells to me like a kernel problem.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately we can't fix it, because your description does not yet have enough information. The message you describe is a very generic message as the result of many possible different problems.

Please include the following additional information, if you have not already done so (pay attention to lspci's additional options), as required by the Ubuntu Kernel Team:
1. Please include the output of the command "uname -a" in your next response. It should be one, long line of text which includes the exact kernel version you're running, as well as the CPU architecture.
2. Please run the command "dmesg > dmesg.log" after a fresh boot and attach the resulting file "dmesg.log" to this bug report.
3. Please run the command "sudo lspci -vvnn > lspci-vvnn.log" and attach the resulting file "lspci-vvnn.log" to this bug report.
4. Please attach your /var/log/kern.log and /var/log/kern.log.0 files to this bug report.

Sorry for not getting the required info to you before, but this is a first time for me. BTW, I have confirmed that in both OS's, the kacpid process is the one that takes over CPU #1.

Attached are the files -- well apparently I need to attach them one by one. So, I'll attach them all as a .zip file. Please note that the server OS did not have a kern.log.0 file.

Please let me know how else I can help.

Hi Chris,

Sorry for not getting back to you on this sooner. I previously run memtest on this computer without errors, but thought it valuable to repeat the test over a longer period. Unfortunately, yesterday I got sidetracked looking at the Olympic games, so I'm only getting back to you with the memtest results. After 36 hours, 52 minutes of clock time and 26.4 passes on 2GB of RAM (and thunderstorms all day yesterday), there are zero errors.

Let me know what else I can do to help.

Hi !
I installed Ubuntu Server 8.04.1 last weekend, and I have almost the same error.

I have compiled the last kernel modules for r8101 (r8101-1.009) and r8169 (r8169-6.007) from Realtek (as I've both cards).

If it can help.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

Just come back from holidays.

I've installed linux-image-2.6.27-* package, and tested the *-server release.

Seems to be better on the D945GCLF board.
I've tested only this evening, but no freeze after several reboots.
2.6.24-19 kernel can freeze in ~10min.

Sorry, no trace of the lock in /var/log/kern.log.

But with my Neatgear GA311 (r8169 chipset), the softlock appends again.

It seems to be cause with the r8169 module.

2.6.24-19 with official r8169 module : freeze with or without GA311 (ie onboard r8101 chipset lan + r8169 card)
2.6.24-19 with last Realtek r8101 module AND r8169 module : freeze with GA311 (r8169) and sometimes without (when r8169 is loaded before r8101)
2.6.24-19 with last Realtek r8101 ONLY (r8169 blacklisted) : NO freeze (but GA311 don't work anymore)
2.6.27-2 : NO freeze without GA3131
2.6.27-2 : freeze with GA3131

Thanks Guillaume for testing with the Intrepid kernel. Dr. John - it would be great if you could test the Intrepid kernel too, to see if you get similar results. You should be able to test just by booting the live CD.

hefaeche - I'm not sure if you have the same issue as described here. There is nothing in your logs to suggest that.

Thanks

I have the same problems on two D945GCLF running Hardy and one D945GCLF2 (Atom 330, dual core) running Hardy and now Intrepid.

Running 64-bit Intrepid server on the GCLF2 (with an old PCI ethernet card):

The more recent kernel, 2.6.27-6, does not boot reliably. It took forever to initialize the nics or locked up at that point with:
BUG soft lockup - CPU #3 stuck for 61s! kstop3:4128
BUG soft lockup - CPU #0 stuck for 61s! kacpid:73
BUG soft lockup - CPU #1 stuck for 61s! kstop1:4126
BUG soft lockup - CPU #2 stuck for 61s! kstop2:4127

Using the slightly older kernel I booted all the way but there are lots of pauses during the graphical boot (I started with -server but added the rest of ubuntu-desktop). I used "noacpi acpi=no" because that seemed to help with Hardy but I'm starting to think that is superstition on my part.
Linux pink 2.6.24-19-server #1 SMP Wed Aug 20 18:43:06 UTC 2008 x86_64 GNU/Linux

My kern.log has several of these boots.

I have the same problem like Mark Lanett posted before, but mybe i have some additional information for you...

First: I have the D945GCLF2 Intel Board, riding Atom 330 dual Core CPU on it, chipset is the old Intel 945 (like D945GCLF Board)

I had no problems running the plain mainboard (without PCI-Cards plugged in) on Hardy and also on Intrepid (actual kernel on both).

I can reproduce soft lockups of the CPUs on hardy AND Intrepid as well, if i follow these steps:

1: Plugin Soundcard in PCI-Slot (soundblaster xifi or terratec Aureon 5.1 PCI make no diff.)
2: Turn on PC
3: everything works fine, on genome systemmonitor are 4 Cores displayed, running fine, soundcard ( terratec) works out of the box
4: shutdown and start or restart
5: System stuckes on booting... every time
6: Unplug Soundcard
7:System starts fine again...

after step 7 you can start from step 1 again... everytime the same... maybe something with recognition of new devices from bios?

i have tested one thing until now....

after not booting up again, i set in grub acpi=no, now ubuntu starts up, but takes MUCH longer, and after looking into system-monitor in gnome, there is only 1 core displayed....

is there any information i can give to you?

sorry for my poor english :)

pico78 (m-nuesser) wrote :

so, i take a deeper look at the problem and attach all the data you may need...

first: information after a clean boot, without something plugged into PCI
second: Information after boot after plugging my PCI Soundcard in

after that second boot, every boot stucks until i unplug the PCI Soundcard

uname -a
Linux Homeserver 2.6.27-7-generic #1 SMP Fri Oct 10 03:55:24 UTC 2008 i686 GNU/Linux

I currently running Debian Lenny on my D945GCLF with last kernel, but the problem seems to be the same.

So, my conclusion => bug with kacpid, due to r8101 or r8169 modules.

In fact, with my Netgear GA3131 card (r8169), or with the onboard r8101 chip, the system freezes when become idle.
If something is running, like "ping www", no freeze. When nothing is running, the system freezes in 1 or 2 minutes.

Last weekend, I turned off the onboard chip, and only use another PCI card with Marvell chip.
Result : no freeze at all in 4 days (24/24 7/7) ... unbelievable !

If someone can confirm this with Ubuntu 8.04.1.

ok, now something cool has happend....

i plugged out the PCI-Soundcard...
restart...
sudo apt-get update, then upgrade, after that dist-upgrade... (huge update... 80-90 MB to download)
shut down
plug pci-soundcard in again
start... no problem...
restart... no problem... thats the magic... everything still works...
testing.... restarting 10 times, no problem starting up again...
testing.... shutdown... plug power cord off, after 10 seconds again on, starting up... still no problems...

maybe after that everything is working? there was a new kernel revision, and also somthing called pcidev......

I'm suffering this, just not in ubuntu. (it's a kernel issue)

2.6.27.1 on Gentoo. The board is D945GCLF2. Works fine if no PCI card is plugged, hangs that way in 1-2 minutes specially not under load. I've tried both a rtl8139 and a rtl8169 pci card. I seriously need the extra NIC, so if any workaround were to be found, that'd help.

I know that it may sound very strange, but could you try to disable automatic fan throttling in BIOS Setup? I have had the same issue and after turning off this option in BIOS it started to work just fine even if temperature is sometimes higher than with automatic fan throttling.

My hw setup:
- D945GCLF2
- 1GB DDR 667Mhz
- PCI Intel Ethernet Pro 100

I use both NICs (onboard and one in PCI slot) 24/7

Kernel version: 2.6.24.5 with boot option pci=noacpi

Hi,

I have a D945GCLF2 with Ubuntu 8.10.

I had fan control enabled too, and it led to freezes when load was high. I have now disabled automatic fan control and I'll see how it goes. Anyway, here's my syslog attached.

On my setup this usually happened during start up. The call to NetworkManager returned and the freeze happened during starting X when the screen was blank and I could not see any messages and could not return to console. -> I have been trying to fix my X setup for days, installing and compiling different drivers and patches and reconfiguring xorg.conf endlessly. Please don't do that if the problem is elsewhere ;) I will try to live with dhclient for now.

My configuration:

Ubuntu 8.10 (2.6.27-11-generic kernel)
Fujitsu Siemens Amilo La1703 laptop (AMD Mobile Sempron CPU)
The WLAN driver is the Windows XP driver inside NDISWrapper

Hello,

the solution for me is the r8169.ko driver with an patch to fix the dropped packets and other issues.
This is reported under https://bugs.launchpad.net/ubuntu/+source/linux/+bug/288845.

For a quick-fix you can download the kernel for hardy (ubuntu 8.04) there http://linuxtrek1.blogspot.com/2008/10/ubuntu-on-intel-d945gclf-with-intel.html.

Tipp - Check the newest BIOS Upgrade for Intel® Desktop Board D945GCLF:

Im using thinkpad_acpi fan controler because of other Ubuntu serious bug - the fan by default is never reaching maximum rotation possible, the bug is reported here:

Hey, have the same note after installing UBUNTU 10.4. Before I had no graphical surface after installation. The same with opensuse 11.2. Research gave me the hint that my combination of a NVidia Mainboard with an ATI Graph card causes this bug. As a solution I found proposals to switch off acpi, or start ubuntu with "nomodeset" I tried all that stuff, but had no positive effect...

I have the same issue here
10.04.1
BUG: soft lockup - CPU#1 stuck for 61s!

When I boot the computer from a fresh install I get this. Sometimes if I let go it will go through but sometimes it won't???
When it goes through I can use Ubuntu like if there was no problem.
I can hear sort of a noise coming from the HD but the activity led does not flash.

Why is this happening.

I'm using old P4 3.0Ghz HT HP Media Center PC m1170n.

Anyone?

I just had this problem when booting automatically through ACPI (RTC alarm). The following solved it for me:

sudo apt-get install intel-microcode

See this blog post: http://smackerelofopinion.blogspot.com/2010/03/installing-intel-microcode-updates.html

Dr. John, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag:
needs-upstream-testing

This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text:
needs-upstream-testing

If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested.

Please let us know your results. Thank you for your understanding.
