Bug Description
package: linux-image-
Linux ubuntu 2.6.24-11-generic #1 SMP Fri Feb 29 21:26:31 UTC 2008 x86_64 GNU/Linux
From time to time (every 10 to 100 minutes) the computer is frozen with no reason. It dosen't matter what i do when it freezes. With no reason, the image is frozen, the mouse is not responding, and i can't switch to any terminals either. It hapends since after updating to the latest alpha a few months ago.
hints: the kernel, a module of the kernel (other than nvidia, ssb or b43), other reasons?

What did you exactly do? Did you try to compile the driver for yourself (what I expect since you have the wlan0_rename device) or are you using the one provided by the new hardy kernel? A driver from upstream git compat-

Yes, i compiled the latest version for myself. I'll install the b43-fwcutter package now to see the diference.
I've put noacpi noapic to the kernel and it still frozes. I've installed the latest kernel update and recent updates and it still do the same but with a diference: i think it is less offten now. My CPU and all temprature mesures show a temprature between 50 and 60 degrees C all the time. So i supose it is not an overheat.

I have reinstalled b43-fwcutter and still have the wlan0_rename. Should i reinstall the b43 driver also?

You should _uninstall_ the compat-
Hardy kernel already includes the b43 and b43legacy drivers, there is no need for recompiling them from the package prepared by linuxwireless.org. The sources on the linuxwireless.
The Versions in 2.6.24 are needing other firmware-version than the ones upstream, so b43-fwcutter from hardy cannot help you in getting to work the compat-
b43-fwcutter package is only for installing the needed firmware, it should call /usr/share/

Ok, in that case it's a misunderstanding. When I asked you if you did install the driver from linuxwireless.org I thought about the kernel-driver (that is linux-wireless-
Does your card work right now? The wlan0_rename issue is of minor importance, though this should no longer happen in hardy. You did a dist-upgrade, right? Maybe there are some left-over config-files from an earlier install, which may cause something like that. If your card works right now, you should not care about it.
moa3333 (moa3333) wrote : | #8 |
Yes, my card works now as well as it was working with the firmwares b43-fwcutter version 11 from the web site.... despite the "_rename".
On the other hand, i observed that this "system freeze" happends more offten when i play the game openttd (using 2D acceletation) than whe just using firefox under 3D acceletated compiz.
I wonder if there is an nvidia problem (with gutsy i had a memory leak, it seems that now there is no more memory leek but also i was not able to keep the computer on more than a few howers to see).
I really have no clue on the real cause of this problem and i don't know how to find because i have difficulties finding the cause of a kernel bug that leaves no trace as far as i know....
moa3333 (moa3333) wrote : | #9 |
I have an intuition it might be related to the buggy nvidia-glx-new drivers. I'll try to investigate this in the next days for confirmation...
Same bug as???

I've installed the latest nvidia driver and it did NOT solved the problem. Now i am back to nvidia-glx-new from ubuntu....

UPDATE:
I've noticed in the last few weeks that some times when the computer was frozen, when pressing the power off button for about 5 secconds, right one second before hard shuting down the system responded.
Since i've tried not to shut it down and i noticed that rarely the system gets back to normal after a few seconds, but not all the time it hapends in a resonable time. I've noticed also that if i let the computer open most of the times it is still working, but not always...
This is in my opinion a good sugestion that it is not a "real" kernel panic but only "like" a kernel panic to the end user. It is actually like the kernel is "busy" for a few secconds or some times for a few minutes and maybe more (i never waited more than a few minutes to see if it gets unblocked then).
A VERY strage thing happend after the last upgrades and my numerous changes to xorg and other... After getting back to the official packages from ubuntu (nvidia-glx-new), compiz was using 100% of the CPU and increased memory usage. It worked ok, but from time to time the mouse stopped responding a few seconds exactly like the in the bug we are investigating here. I've manged to resolve compiz CPU by changing a bit the settings and killing compiz.real a few times (i'll have to reboot now to see what happens then).
I have a feeing this bug is actually related to compiz and nvidia (maybe only on AMD64). And it is not a real kernel bug or panic. I saw other poeple experiencing complete blocking of the mouse and of the computer for a few secconds in compiz. In my case, the bug blocked the computer and the mouse for a VERY long time most of the times and some times for only a few seconds.
I wonder if this is a compiz / nvidia busy-bug instead of a kernel freeze-bug? God, i hate compiz and this buggy nvidia drivers...
moa3333 (moa3333) wrote : | #12 |
I've done a one pass memory test, no errors.
I've uninstalled yesterday nvidia and used nv driver with metacity and without compiz since. It behaved ok yesterday but today i had a freeze right a few minutes after i started my laptop.
I had also a problem with the wifi card: it was working only 20% of the time, the rest of the time network was unreachable! I have disabled encryption and now it seems to work fine. If there is no more crash in the next days it means the WPA Parsonal encryption in the b43 firmware or driver was causing the system freeze, l'll keep you up to date.

Using no encription and the nv driver i got a system freeze....
moa3333 (moa3333) wrote : | #14 |
I have installed ndiswrapper instead of b43 and ssb... My computer still freezes.
Conclusion: it is not a problem of b43 or of nvidia. Since i have done no other change, it is surely a problem caused by the upgrade from Feisty to Hardy, most probably the kernel itself or a new module in the kernel.

I have observed a few facts:
* the freeze happends "more offten" when i use compiz play a game or watch a video (this is true even when using nvidia driver without compiz)
* when the freeze hapeneds, if i reboot my computer, some times it will continue to hapend after only a few minutes
* once my computer restarted itself right after i restarted it manually but before entering the linux kernel!
Then i remember the history of this laptop: my video card was broken after i bough it and they replaced it with a new one for free 9 months ago. It is possible that this manual operation could have resulted in a badly mounted video card causing some times overheat to the graphical GPU not to the main CPU.
I have two "feelings":
* first of all, my feeling that this is related to nvidia driver or compiz is true in some way......
* seccond, nvidia or compiz seem to be not the cause but only what trigers the problem to occur more offten...
I have a HP Pavilion DV6000 laptop, for whoever plan to buy HP crap in the future....
If no one else is experiencing this in ubuntu, then i feel i should set this bug's state to invalid.

Hardy Beta (with all latest updates) on my Compaq v3000 seems to have this problem. So you are not alone!
The laptop randomly freezes mostly resulting in a hard reboot. But recently i just switched off the wireless antenaa and after a few minutes it starts responding! I have been able to reproduce this behaviour atleast twice.

Ok, that's good.
Actually i have noticed after a few days of using kernel 2.6.22 i was not able to reproduce the freeze.
Comming back to the last kernel 2.6.24 is causing the problem to come back.
I am using ndiswrapper, and don't know if it's related to it or not, but one think is sure: kernel 2.6.24 does this.
What is your kernel? Does the error occour also with ndiswrapper?
jyks (jyks) wrote : | #18 |
kernel version: 2.6.24-12-generic.
I'm not using ndiswrapper, rather using the b43 driver.
I'll check if this occurs with ndiswrapper & kernel 2.6.22.
Onkar Shinde (onkarshinde) wrote : | #19 |
I can confirm the bug. It is caused by some combination of modules b43, rfkill, rfkill_input. I have observed the problem in 2.6.25 kernel image available in repositories as well as unofficial 2.6.27 kernel image created by Michael Casadevall (NCommander/
Following are my observations on my ibook powerpc with broadcom 4306 chipset based wireless NIC.
1. The UI freezes randomly. At no point it returns to normal state. Most of the time the computer reboots automatically after some time.
2. If I am using console (Ctrl + Alt + F1), at the time of panic I see some messages related to either rfkill_input or b43_interrupt_
3. Yesterday I unloaded all the modules I have mentioned (modprobe -r) and I didn't get any UI freeze for more than four hours. I was connected to internet via wired NIC, watched movie using a DVD, had chats with friends, upgraded the machine with latest updates. No problems at all.
I plan to blacklist the modules one by one so that I can identify which actually causes problem. Also If I get the kernel panic message, I will take a photo and attach to this bug.
Hope this helps.

In my case, the problem was also present when not using b43. since then i only use ndiswrapper with the windows driver working much better than the free driver. I never tried to look at rfkill* modules....
However, in my case, this is a probem occuring in all operating systems (knoppix, debian, gentoo, etc) with kernel 2.6.24!
In the meantime i used kernel 2.6.23 then 2.6.25 on Sidux (debian Sid) and then kernel .6.26 on a few systems, and now i am usgin kernel 2.6.27. I NEVER had any problem with this kernel (using ndiswrapper or wifi) but if i boot in knoppix or any other live cd like Systel Rescur CD using kernel 2.6.24 the problem is confirmed over and over again at random imtervals.
since this problem NEVER occured on any other kernel, older or newer than 2.6.24, i just suppose it was caused by a regression in 2.6.24, regression that was fixed in 2.6.25 and later kernels.
If you have this problem in other kernels than 2.6.24 then it might not be the same problem. I'm so satisfied with newer kernles for fixing this annoying problem in my case.
Greetings.

@moa3333,
Do you have any powerpc machine around where you can check if the problem is present on 2.5.25 or greater kernel versions. It is possible that it is fixed for 386 but not for powerpc.
moa3333 (moa3333) wrote : | #22 |
Actually i think the problem is not even present on i386...
I only had this problem on my AMD64 Turion PC, not on my i386 one.
Maybe the problem on AMD64 was fixed and it is now present on powerPC?

moa3333, thank you for reporting this and helping make Ubuntu better. Hardy desktop reached EOL on May 12, 2011.
Please see this document for currently supported Ubuntu releases:
https:/
We were wondering if this is still an issue on a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://
If it remains an issue, could you run the following command in a supported release from a Terminal (Applications-
apport-collect -p linux <replace-
Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https:/
Thanks in advance.
