kernel oops: invalid opcode 0000

[useResa]

This bug report derives from discussion at http://ubuntuforums.org/showthread.php?t=832383

The symptom is that laptops randomly lock up with caps-lock and scroll-lock flashing and need to be hard rebooted, usually by leaning on the power switch.

There are no messages in the logs.

A serial console to another machine reveals that the oops is coming from the iwl4965 wireless driver.

The same thing happens to me.

I'm running Hardy on Acer Travelmate 660 (Intel 1.4, Intel 855GM graphics and Intel wireless) and before the last update (Kernel 2.6.24-19-generic) everything worked perfectly, absolutely no issues.

After the update, my system is [B]COMPLETELY UNUSABLE!!![/B]

I'm getting hangs on everything. Random program crashes, Segmentation faults, X resets, X freezing, complete system freezing, even GDM sometimes crashes. The SysRq keys sometime work and sometime the only solution is hard-reset.

I've ran Memcheck and it reported no errors. Also, before the update there were no crashes. I've tried downgrading to 2.6.24-18-generic but it's the same. I don't know what else got upgraded so I cannot revert to test.

I've also tried both intel and i810 driver and it makes no difference.

I've attached a stack trace from firefox that I've managed to catch and an excerpt from /var/log/kern.log

Please help! I'm ready to supply any debugging info / logs that might help and ready to try installing/removing and generally messing with the system until it works because it's unusable in it's current state.

The following similar bug reports seems to pointing at the same symptoms when using Wireless-LAN...
List of symptoms:
    * Screen and mouse become frozen
    * Caps Lock LED BLINKING
    * Scroll Lock LED BLINKING
    * ...only way out is to reboot by unplugging batteries and power adapter.
    * My notebook is OK as long as I use the built in cable-LAN adapter.

Here's the text of the kernel panic from my D630. Please escalate, it is in the iwl4965 code so it will be hitting a lot of machines.

[Roger E Critchlow Jr (rec)]

Hmm, perhaps this bug report is too confusing.

This bug is a kernel oops from intel 4965AGN driver.

Probably started with the 2.6.24-19 kernels, kernel panic text caught yesterday with 2.6.24-20 kernel.

Description: Ubuntu 8.04.1
Release: 8.04

linux-ubuntu-modules-2.6.24-20-generic:
  Installed: 2.6.24-20.29
  Candidate: 2.6.24-20.29
  Version table:
 *** 2.6.24-20.29 0
        500 http://us.archive.ubuntu.com hardy-proposed/main Packages
        100 /var/lib/dpkg/status

What I expected to happen is that the computer should continue to work.

What happens is that the computer locks up with caps- and scroll-lock flashing.

There is no trace of this oops in the system logs. The panic was collected over a serial console connection.

I attach a complete console log from boot to oops, there is a message from the iwl4965 driver immediately preceding the oops.

[Roger E Critchlow Jr (rec)]

I have downloaded the 2008-07-30 release of compat-wireless-2.6.24.tar.bz2 from http://linuxwireless.org/en/users/Download, unpacked, built, installed, and rebooted to bring up the new drivers.

The output of /sbin/modprobe -l iwl4965 confirms that the system found the new drivers.

I get essentially the same oops from this version of the driver. The path name of the driver source in the attached oops has moved from:

/build/buildd/linux-ubuntu-modules-2.6.24-2.6.24/debian/build/build-generic/wireless/iwlwifi/iwlwifi/compatible/iwl-4965.c

in the previous oops to:

/build/buildd/linux-backports-modules-2.6.24-2.6.24/debian/build/build-generic/compat-wireless-2.6/drivers/net/wireless/iwlwifi/iwl-4965.c

[Roger E Critchlow Jr (rec)]

linux-backports-modules-2.6.24-20.21 did not fix this problem, even with the 4965 microcode renamed it generates essentially the same oops.

[Nitesh Mistry (mistrynitesh)]

I don't have any wireless connection on my desktop (I have wired broadband connection), but still I face this problem - the only variation being that the NumLock and CapsLock do not flash.

[Roger E Critchlow Jr (rec)]

Because there are iwl4965.ko modules installed for both linux-ubuntu-modules and linux-backports-modules, I picked the wrong module.

[Roger E Critchlow Jr (rec)]

This problem persists with the linux-backports-modules-2.6.24-20.23-generic package released today. I attach the kernel oops generated when this release oopsed.

[Roger E Critchlow Jr (rec)]

Could we please get some attention paid to this problem?

People with totally generic hardware, Dell Latitudes, are abandoning Ubuntu because it -- the latest long term support release -- crashes when they attempt to use the wireless.

There's no sign that any Ubuntu developer has even read this bug report.

Why? Did I fail to include some essential ingredient?

What more do you need than a kernel oops with a smoking gun pointing at the iwl4695 driver in it?

[Soroosh Radpoor (ssh-rdp)]

I just tested with latest kernel (2.6.27-1-generic from kernel.ubuntu.com/pub/next), and I still get some random crashes (blinking caps lock, screen freeze,...) while using my iwl4695 card (I use an external wireless card as a workaround). Is there anything I can do?

[Roger E Critchlow Jr (rec)]

This problem persists with linux-backports-modules-2.6.24-21 version 2.6.24-21.25, kernel oops attached.

The system ran over 48 hours with the new kernel, without the backports, with the wireless active, and had not crashed.

With the backports installed, the system lasted less than 3.5 hours before crashing.

[zshift (zshift)]

I have a sony vaio laptop (fw139e) with following specs:

ati hd3470
atheros ar928x wifi (802.11n)
core 2 duo p8400
centrino 2 (pm45 chipset)
3gb pc2-6400 (2/1gb)

I have the same issues. I don't believe this is due to intel/nvidia. this appears to be faulty on the networking side. i've also noticed it only works on certain connections. at home, cable works fine (so far). at school, crashes (florida international university). will try at my GFs house, she has adsl. also, when i first install compat-wireless driver (latest build for "old" kernel) it works after installing and running "make unload" then "sudo make load ath9". works fine for hours. after rebooting, wont last me 15 minutes.

[Scott Armitage (scott-armitage)]

I am experiencing this same problem on a Lenovo Thinkpad T61:

nVidia Quadro NVS140M
Intel 4965 wireless (802.11N)

I'm running the Intrepid Ibex beta:

$ uname -r
2.6.27-7-generic

[Roger E Critchlow Jr (rec)]

There's a new bug for this problem filed against the Intrepid Ibex kernel:

  Bug #275359 in linux (Ubuntu): "kernel BUG at
/build/buildd/linux-2.6.27/drivers/net/wireless/iwlwifi/iwl-tx.c:1198!"<https://bugs.launchpad.net/ubuntu/+source/linux/+bug/275359>

you should let them know of the additional hardware having the problem.

I just had the same symptoms: mouse freezes, scroll and caps lock blink. After a minute or so the system automatically hard rebootet.

I found this through an ubuntuforums thread http://ubuntuforums.org/showthread.php?t=832383&highlight=flash+64+alpha On this thread many reported bugs are mentioned many of which may be duplicates of each other.

I have been following bug#293200 these at first glance appear to be dups.

[Larry (orbish)]

I would like to confirm this issue with the following card on a Dell Latitude E6400:

0c:00.0 Network controller: Intel Corporation PRO/Wireless 5300 AGN [Shiloh] Network Connection

Crashed with 9.10 virgin install as well as daily build 10.04 (12/15/2009).

Subscribed!

I've only tried it with Wireless-N because, why downgrade? Subscribed. Linux die-hard for 3 years running, you can reach me behind bars @ Windows7.

[Tamran (tamran-lengyel)]

Has anybody tried this?

http://baheyeldin.com/technology/linux/intel-wireless-wifi-link-5100-iwlagn-kubuntu-karmic-koala-910.html

I have read countless pages with this problem on Kubuntu 9.10 and the default drivers. I disabled the wireless and had an uptime of over a week. I gave the wireless (I have an N router) and within 5 minutes it failed flat with a kernel panic. I also tried the backports to no avail (although it seemed to reduce the frequency).

My lsmod and lspci are attached.
