iwl4965: Microcode SW error detected. Restarting 0x2000000

[Matt Zimmerman]

Occasionally, my wireless interface stops working, with the following message in the log:

Mar 10 09:30:45 perseus kernel: [37783.753286] iwl4965: Microcode SW error detected. Restarting 0x2000000.

When this happens, the interface stops passing traffic, and I'm unable to associate with any networks. Unloading and reloading the module is the only thing which gets it working again. This is on a ThinkPad T61 with a hardware kill switch and the following wireless device:

In my case, network manager didn't know the connection down, but when I told it to reconnect to my SSID, it was able to, without having to go through to cycle the driver with modprobe.

[Michael R. Head (burner)]

Also, for me, it (only) seems to happen when I'm accessing another machine on my local network via VNC through an ssh tunnel, so maybe there's something related to that pattern of traffic.

[Matt Zimmerman (mdz)]

Note, the patch in the linked (fixed) upstream bug is from 2006; it's hard to believe it isn't already in our tree. This would seem to hint that this is a different bug.

[Michael R. Head (burner)]

Ah... I looked at the last few comments, and I was under the impression that it was fixed in 1.2.1 (hardy has 1.2.0), but now that I take a second look, I see that it was meant to have been fixed in 1.1.2.

I guess it's a pretty general error message.

[Elie De Brauwer (elie)]

I've only seen this error myself one of twice (on a period of a month) and I haven't been able to reproduce it either.

[Brian Murray (brian-murray)]

This watch seems more likely to be the same bug as it has the same restarting information. The upstream bug reporter indicates they were authenticating via radius. Is that the case for anyone in this bug report?

[Elie De Brauwer (elie)]

Not for me, I was connected to my wrt54g using a mere WEP (i know, i know, but ndiswrapper driver in another laptop doesn't support wpa). I was actually connected for quite some time and i ended up with this error out of the blue. But i must admit i have only seen it twice and that is currently already a month ago

[Michael R. Head (burner)]

My router is a (hardy) Ubuntu box which has an atheros-based card in Master mode running hostapd. I've configured hostapd with a WPA-PSK (not WPA-RADIUS or EAP), and I'm using TKIP and CCMP ciphers.

[Leann Ogasawara (leannogasawara)]

Hi Everyone,

An updated version of the iwlwifi drivers (version 1.2.25) was recently added to the linux-backports-modules-2.6.24 package:

https://bugs.edge.launchpad.net/ubuntu/+bug/200950/comments/30 .

It would be good if you could retest once lbm with the update is published and available. Thanks.

[Barteq (barteqpl)]

Good news. I've just got this error right now, want to confirm and voila - it's already patched. So waiting for package to be published.

[Tim Gardner (timg-tpi)]

Added iwlwifi 1.2.25 to LBM. Also updated i4965 firmware to 4.44.1.20.

[Michael R. Head (burner)]

Why would iwlwifi go to LBM and not LUM? I thought LBM was for backports which would only appear post-release?

[Tim Gardner (timg-tpi)]

Intel only warrants iwlwifi 1.2.0 for Centrino brand certification (which is important to Dell etc). Also, its pretty late in the release cycle for a major iwlwifi upgrade. Placing the upgrade in LBM allows folks to choose their poison.

Hi

I have recently updated to amd64 Hardy 8.04 from 7.10 and started noticing that my dmesg is full of warnings and errors related to iwl4965 module. I've installed the latest updates and linux-backports-modules-hardy-generic package.

The errors happen every time i use the Fn+F5 switch on my Thinkpad T61p laptop. As i remember, Fn+F5 didn't work at all on Gutsy, however, in Hardy it seems to partially work. By partially I mean the following: when I turn on the laptop, both wi-fi and bluetooth is enabled and leds are on. Pressing Fn+F5 once will switch off the wireless, pressing it again would switch off Bluetooth and once more would try to activate the wireless again. The dmesg errors start happening when I try to switch on wireless. The summary of dmesg errors:

Hello,

So that's what t he Fn+F5 key is for, i can completely reproduce the symptoms you describe on an Lenovo R61, this is my output after repetitively striking Fn+F5 (I wasn't making use of wireless here, the interface was in a down state.

[Michael R. Head (burner)]

linux-backports-module-hardy has an updated version of the iwl4965 driver (1.2.25) that appears to resolve this for me.

[Mozg (andrei-arhont)]

I have installed the latest upgrades, including linux-backports-module-hardy with version 1.2.25. As I can see from dmesg when the iwl4965 modules is loaded:

[ 31.475785] iwl4965: Intel(R) Wireless WiFi Link 4965AGN driver for Linux, 1.2.25

Elie De Brauwer: Do you use 1.2.25 as well?

[Elie De Brauwer (elie)]

No I used what came with hardy

[ 24.790451] iwl4965: Intel(R) Wireless WiFi Link 4965AGN driver for Linux, 1.2.0

but i'll give the backports version a try.

[balmy_fool (balmy-fool)]

I can confirm that this bug still exists with the latest backports version. I'm seeing it a few times each day. One of my errors was an HW error, I'm not sure what this means.

Here are some excerpts from my logs. All of these showed up with nothing else in the logs for about 20 minutes beforehand, so I don't have any useful context.

The version, from the logs:

I have the latest firmware.

[Thomas Zander (thomas-e-zander)]

I can second that. The problem definitely still exists with the latest backports version.
Machine is a Dell XPS M1330 notebook.

I did not yet spot a "Microcode HW error" like balmy_fool, but I do get two different SW errors:

[

[balmy_fool (balmy-fool)]

I've been trying to capture debug information about the microcode errors, but I haven't had one in a while.

Can someone who is regularly having the errors add this to /etc/modprobe.d/options?

options iwl4965 debug=0x43fff

It should give more information in dmesg on the nature of the bug, so that it can be fixed upstream.

[Bård Kalbakk (kalbakk)]

Experiencing the same thing here on high load, even with the latest linux-backports-module-hardy package(2.6.24.16.18)
"iwl4965: Microcode SW error detected. Restarting 0x2000000"

(Connected to a D-Link di-624+ with a 54Mbit connection)

I did load the iwl4965 module with debug=0x43fff , but I this doesn't give me more debug info
/sys/module/iwl4965/parameters/debug = 0x43fff so I really don't know why I don't get more kernel msgs.(?)

Any clue?

The bug is 100% reproducible on my IBM Thinkpad T61P, so I'm more than willing to do some more work if necessary.

[balmy_fool (balmy-fool)]

I found the same problem with debug=0x43fff not working, and have reported it as Bug #226593.

[Bård Kalbakk (kalbakk)]

This bug was fixed in 2.6.25 early february.
Please see git-commit d68ab68066805fdfee1f5f29ec2ec0179fd92fe1
http://git.kernel.org/?p=linux/kernel/git/linville/wireless-2.6.git;a=commitdiff;h=d68ab68066805fdfee1f5f29ec2ec0179fd92fe1;hp=c342a1b91f6ccd317c68defd3b4c7bb75397d967

I applied this simple fix to linux-backports-modules-2.6.24-16-386, and iwl4965.ko has not failed yet.

Please consider applying this patch to Hardy, if you're not going for kernel 2.6.25.

[Sean Dague (sdague)]

This bug is marked as fixed in backports, but I'm running the hardy backport kernel, and have managed to get knocked off twice already with the same error.

[Michael R. Head (burner)]

I've been running the hardy backport version for some time, and it seemed to have been working OK, but after a recent (past week or so) update, I'm seeing this again very frequently.

[Michael R. Head (burner)]

This may be related to http://intellinuxwireless.org/bugzilla/show_bug.cgi?id=1576 which has a small patch attached: http://marc.info/?l=linux-wireless&m=120242061211544&w=2

[Michael R. Head (burner)]

Well, I tried the patch (with a apt-get source linux-ubuntu-modules-2.6.24-19-generic, application, dpkg-buildpackage -us -uc, dpkg -i), and it was no help to me on my T61p. Actually, it seems to make matters worse: instead of the connection dying every few minutes, it dies after a second or two.

[petter wahlman (petter-wahlman)]

This is still an issue with my Lenovo R61i on Hardy with backports.
My network link goes down after a few minuttes of heavy network activity.

[Leann Ogasawara (leannogasawara)]

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.

[Mark Mandel (mark-mandel)]

Just to add an extra note here - sometimes this drops off my internet connection, but quite regularly this also results in a kernel panic on Hardy. This can occur more than once per day.

The strange thing is, it will generally only panic when I'm at home - I can only assume that it's because I'm in an apartment building, with multiple other wireless networks around, and other interference.

I'm not running backports yet, but will probably plan on moving to Ibex when Alpha6 comes out, to try the new kernel, and see if that solves the issue.

Also happy to do any further debugging if required.

[Anand Vaidya (anand-vaidya)]

I have the same problem IWL4965 1.2.0 driver Kubuntu 8.04

I notice that, when the laptop is booted, the interface works fine.

When I suspend / resume a few times, typically after 3 days, the wlan0 interface will stop. Only a reboot recovers. The error message is:

iwl4965: Microcode SW error detected. Restarting 0x2000000.

[Mark Mandel (mark-mandel)]

I just wanted to confirm that this has been fixed for my in Ibex.

I did a clean install of Ibex, and haven't seen it since.

[Leann Ogasawara (leannogasawara)]

@Mark Mandel, thanks for testing and the udpate.

Can anyone else confirm this is resolved with running the Intrepid 2.6.27 kernel? Thanks.

[balmy_fool (balmy-fool)]

I can confirm that the problem still exists in Ibex. I get regular Microcode errors. To recover I have to unload and reload the module.

Also, on occasion, when I unload and reload the module, my computer mostly freezes. I can't start programs and shutting down doesn't work. This may just be general module unloading flakiness.

I've posted a recent dmesg with microcode errors. I'm currently trying backport-modules, which seems no better than the standard module.

See also bug 282355, where I posted dmesg for some past Microcode errors.

[balmy_fool (balmy-fool)]

In fact, that last post was followed quickly by a microcode error. I got the dmesg. This time, I accidentally left clicked on the network manager icon and my computer solidly froze, responding to nothing.

How do you enable debugging output for iwlagn? Does it even work with the ubuntu compile? I remember it being disabled in earlier kernels.

[Jeffrey Baker (jwbaker)]

I confirm that this is NOT fixed in Intrepid, at least not on iwl3945.

[balmy_fool (balmy-fool)]

I've put the following into /etc/modprobe.d/iwlagn

options iwlagn debug=0x43fff

Hopefully I can give more useful information the next time it crashes.

[Adam Porter (alphapapa)]

May I propose increasing this to high priority? Causing lockups is serious, and many laptops have these chipsets.

[qbanin (qbanin)]

I think this issue is somehow related to interrupt sharing. I have Nvidia 8600M graphic card and my problem with Microcode errors and networking restart started, when i've added the line "options nvidia NVreg_EnableMSI=1" to /etc/modprobe.d/options.conf

After disabling this option I have no more "iwlagn 000:0c:00.0: Microcode SW error detected. Restarting 0x92000000" messages.

[James Ward (jamesward)]

I'm not seeing this anymore on the latest karmic.

[Philipp Ehses (philipp-ehses)]

I'm actually still experiencing this bug on the latest karmic live cd (even after an apt-get upgrade which only pulls in some ubiquity changes anyway).

 It seems that I'll stay with opensuse a bit longer than expected...

[Philipp Ehses (philipp-ehses)]

Hey Jordi, thanks for suggesting a very obvious and simple solution - just using a different u-code ;-)

I just copied iwlwifi-4965-1.ucode and iwlwifi-4965-2.ucode from my opensuse partition to the ubuntu partition and it seems to work just fine! I have attached all iwlwifi firmwares I found in opensuse in case anyone else wants to try this. Btw Jordi, copying the firmware into /usr/lib/firmware should be everything you need to do (apart from reloading the modules which you can do with rmmod/modprobe or - easier - a reboot).

[Philipp Ehses (philipp-ehses)]

for iwl4965

[Philipp Ehses (philipp-ehses)]

for iwl4965, part 2

[Philipp Ehses (philipp-ehses)]

for iwl4965, part 1 - the readme was a mistake ;-)

[Philipp Ehses (philipp-ehses)]

and especially for Jordi: iwl5000

Hope this works for you, too!

[Philipp Ehses (philipp-ehses)]

Sorry, the firmware files are of course stored in /lib/firmware.

And make sure to backup the old files before you try this!

[Steve Langasek (vorlon)]

Philipp,

What package and at what version are these firmware images part of in OpenSUSE? We can't exactly take firmware that you're passing to us on Launchpad and ship it in Ubuntu - this Intel firmware is subject to copyright, and we need to know what this firmware is before we can even consider distributing it to users.

[Philipp Ehses (philipp-ehses)]

Hi Steve,

sorry, I wasn't aware of the licensing issue.

The firmware comes from openSuSE 11.1. I did a quick search and found out that they are included in the following (rpm) packages:

iwl3945-ucode
iwl4965-ucode
iwl5000-ucode

zypper info returns this (shortened)::

Name: iwl3945-ucode
Version: 15.28.1.8-1.7

Name: iwl4965-ucode
Version: 228.57.2.23-1.1.1

Name: iwl5000-ucode
Version: 5.4.A.11-2.9

I had a quick look in the README and LICENSE files which come with the firmware, and it seems that redistribution is allowed as long as the binaries are unchanged and the license files are attached (which I can easily provide, or we can just get the rpm packages which include them as well). Here's an excerpt:

Hi Brett,

sorry, just to be sure: Did you copy *both* files ('iwlwifi-4965-1.ucode' and 'iwlwifi-4965-2.ucode') into /lib/firmware *and* rebooted the system (reloaded iwlagn)?

Is it the same 'Microcode SW error detected' error message from dmesg?

[Wiktor Stasiak (wiktor-stasiak)]

These files didn't help me either, still "SW error..."

Additionally I suffer from kernel panics somewhere in iwlagn driver :(

It is still the same SW error and, yes, I copied both files. Although,
all I need it the -2. It supersedes the -1. However, there is one
difference, my software error is a 0x8200000 error code, not the
0x2000000 in this bug report. Though, nobody has posted an 0x8200000
error code, so I was just hoping one would fix both problems.

I've had this problem for quite some time and I was hopeless. I was going to buy PCMCIA card so I can enjoy wireless.

The easiest way to get this error was just start a torrent download that oppens many connections, in about 1~2 seconds the error appears.

The good news is that after upgrade to 9.10 it apears no more. I managed to complete a download and the connection is still up and running.

[Brett (breusshe)]

I just found another bug report on RedHat's website. It actually had my
exact error code:

https://bugzilla.redhat.com/show_bug.cgi?id=519154

Comment #10 suggests passing the option swcrypto=1 during module load.
So, I did as comment #11 suggested:

echo option swcrypto=1 > /etc/modprobe.d/iwlagn.conf

So far, so good. No errors. I'll let ya'll know if that changes.

[Brett (breusshe)]

well, nevermind. Wireless just died. Sorry for the false alarm.
However, not a complete let down. My connection lasted for about an
hour and a half. Usually I only get seconds before it goes down. Maybe
that swcrypto=1 is a clue to the problem.

If this is the exact command you typed, then this was a complete no-op. You
must also specify the module name as part of the 'option' command in
/etc/modprobe.d config files.

Yeah, I know. I did the following command:

options iwlagn swcrypto=1

I also ran modprobe -v iwlagn when I reloaded the module, the option was
definitely applied.

Just to clear things up, this was the error message I was getting:

iwlagn 0000:0c:00.0: Microcode SW error detected. Restarting 0x82000000.

The u-code files from opensuse fixed this bug completely for me - weird that I'm apparently the exception...

[Brett (breusshe)]

Yeah, that is the exact same error I was getting, too. Right down to
the 0x8200000 error code. And it sorta fixed it. Just not completely.
Like I said, it took 1.5 hours for the connection to drop when I usually
only get a few seconds.

Hi all. Hi Philipp Ehses. Please tell me version of the firmware (iwlwifi-3945-1.ucode and iwlwifi-3945-2.ucode). I download them from http://intellinuxwireless.org/?n=downloads&f=ucodes_3945. While that does not work. I apologize for my english. : (

[Mikael Nilsson (mini)]

Fully reprodicible here, on 2.6.32-14, intel 5300 and iwlagn. The connection seldom works longer than 10-15 minutes under heavy load (connected to an "n" router). After the Microcode erroe, the connection is sometimes completely broken, or works at a significantly lower speed (100Kb/s instead of 5Mb/s)

This has happened on and off during my last couple of kernel upgrades. Sometime in the 2.6.31 series it worked, then it started crashing, then some 2.6.32 version worked but now I have problems again....

[Tom Gelinas (tomgelinas)]

I'm confirming Mikael Nilsson's report with my Intel 5300 on 2.6.32-19.

[Tom Gelinas (tomgelinas)]

sorry, I actually have a 6300. It works for hours under light use (barely over 1 Mb of traffic) but becomes very slow under heavy load. Cycling the rfkill switch allows it to work again, it never performs well under heavy load, though.

[Tobias McNulty (tmcnulty1982)]

I have the following controller in a ThinkPad T400s:

03:00.0 Network controller: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection

When I try to connect to a P2P network I get loads and loads of these in dmesg:

[ 622.045142] Registered led device: iwl-phy0::radio
[ 622.045185] Registered led device: iwl-phy0::assoc

[ 622.107866] iwlagn 0000:03:00.0: Microcode SW error detected. Restarting 0x2000000.

It takes forever to connect and sometimes fails completely. When it fails, all other bets are off and I have to reboot before I regain usage of the card. reloading the module might work too but i haven't tried that yet.

** short version of this comment: ** cipher CCMP seems to get better results.
Try WPA2 Personal with TKIP+AES on your linksys **

Hi. I'm crossposting this info to a handful of bugs (since I'm so ecstatic).
I experienced a very similar problem (very frequent disconnects, ThinkPad W500 with iwlagn (device is "Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection [8086:4237]").
I was getting the "Microcode SW error detected. Restarting 0x2000000." messages with the IWL Error Log Dump. I didn't need to unload module to reconnect, just need to select my AP in NetworkManager again (even though NM thinks it's still connected).

Everything was fine on RHEL5, everything was fine when I reloaded to F13.
Upgraded to F14, and the problem started.

Here's what I did which made the problem go away (for me) without resorting to swcrypto=1. Note, I already had both disable_hw_scan=1 and lln_disable=1 set in modprobe.d/wireless.conf.

Since the problem is reported sporadically but deterministically (ie, same users, and for those users, always at the same APs), and responds to swcrypto=1, I decided to change ciphers.

My Linksys WRT54GS (v7 hardware, v7.5.2 firmware) was set to do WPA PSK with TKIP. So sudo iwlist wlan0 scan showed:
                    IE: WPA Version 1
                        Group Cipher : TKIP
                        Pairwise Ciphers (1) : TKIP
                        Authentication Suites (1) : PSK

I changed it to WPA2 PSK with TKIP+AES. The problem went away immediately. Now sudo iwlist wlan0 scan shows:
                    IE: IEEE 802.11i/WPA2 Version 1
                        Group Cipher : TKIP
                        Pairwise Ciphers (2) : CCMP TKIP
                        Authentication Suites (1) : PSK
                    IE: WPA Version 1
                        Group Cipher : TKIP
                        Pairwise Ciphers (2) : CCMP TKIP
                        Authentication Suites (1) : PSK

So I suspect the hardware crypto bug is in TKIP. Here's the tail end of my wpa_supplicant.log (which hasn't changed in around 2 hours, but was repeating the DISCONNECTED event loop quite often before (paranoid redaction with XX):
Trying to associate with XX:1c:10:b0:b5:1f (SSID='XXlinNet2' freq=2447 MHz)

I was having no problem ...
