Hi,

I have exactly the same kernel error message now and then. It basically kills my wifi until i restart. How can I help?

[Martijn de Nerd (martijn-de-nerd)]

To be more precise: I have this message quite often, and sometimes it kills my wifi.

[Jamie Strandboge (jdstrand)]

I too see this under heavy network load on an up to date Lucid on my Lenovo Thinkpad x201s. This uses the same driver and is the same model but slightly different lspci output. It works mostly ok, then will drop the connection completely, causing network hangs. Eventually it comes back on its own.

A little more information:

The following bugs indicate this may be a firmware issue when using hwcrypto with the 4965:
http://forums.fedoraforum.org/showthread.php?t=225729
https://bugzilla.redhat.com/show_bug.cgi?id=519154#c8

http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2052
http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2111

Updating to use swcrypto=1 does not prevent the error and fiddling with the power settings as suggested in the fedora does not help either.

To try swcrypto=1, I did:
$ cat /sys/bus/pci/drivers/iwlagn/0000\:02\:00.0/driver/module/parameters/swcrypto
0

Added the following to /etc/modprobe.d/iwlagn.conf:
# https://bugs.launchpad.net/ubuntu/+source/linux/+bug/571857
options iwlagn swcrypto=1

Then did:
$ sudo rmmod iwlagn
$ sudo modprobe iwlagn
$ cat /sys/bus/pci/drivers/iwlagn/0000\:02\:00.0/driver/module/parameters/swcrypto
1

Although my machine has a different wifi card (same as comment #23), I have the same problem. I can easily reproduce it because on my new HP 8540p it never ever worked. I have had mixed results with adding swcrypto=1 to the driver: sometimes it works, sometimes it doesn't.

However, *if* it works, it works like a charm, and continues to work during that session.

I'm using a 10.04 live CD, 32 bits.

Same symptoms and same hardware as in #23

[penalvch (penalvch)]

Lukas Koranda, thank you for reporting this and helping make Ubuntu better. 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? Can you try 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 run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

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

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://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. 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 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

[Po-Hsu Lin (cypressyew)]

Closing this bug with Won't fix as this kernel / release is no longer supported.
Please feel free to open a new bug report if you're still experiencing this on a newer release (Bionic 18.04.3 / Disco 19.04)
Thanks!
