ubuntu 22.04 kernel 5.15.0.x iwlwifi cannot load firmware, wifi card does not work: Intel Corporation Wireless 7260

[SZ]

With ubuntu 20.04, it worked.
After upgrading to 22.04, stopped working.
I have 2 pcs. of HP zbook G2, they both have the same error after upgrade.
Can't work!!
Booting back to old linux kernel 5.13.x wifi works again!
No windows installed, not a dual boot.

I have other older hp laptop which has a different wifi card, that works well with the new kernel.

Please fix this bug.
Thank you!

I don't think it is a firmware file error, as when booting with 5.13 kernel (left there from 20.04) it loads the same firmware file and wifi works.
With 5.15 kernel, it fails.

Status changed to 'Confirmed' because the bug affects multiple users.

Thanks for the bug report. Can you test the kernel from here:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15/

Specifically:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15/amd64/linux-image-unsigned-5.15.0-051500-generic_5.15.0-051500.202110312130_amd64.deb
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15/amd64/linux-modules-5.15.0-051500-generic_5.15.0-051500.202110312130_amd64.deb

And post the output of dmesg?

[SZ (anari77)]

Hi,

Thank you, I will soon try.
Although I see that the matching linux-modules*-extra*-5.15.xxx pkg not
available for download there...
Without the modules extra I will not have sound and other devices working.
Also I need the matching kernel-*headers* to build the nvidia module via
dkms.
Could you please post those 2 pkgs as well?
Thank you!

Hi, I booted the test kernel, but got no nvidia, so no X GUI.
I saved the dmesg file on the console.

I have attached the full dmesg output as text file.

iwlifi module loads and shows no error, but I could not test yet the wifi network without gui.

[dev Jedice (devjedice)]

found a workaround on an old page, and it is working for me:

https://dev.getsol.us/T3790#68643

add the intel_iommu=off kernel boot parameter in GRUB

[SZ (anari77)]

Hi, having a workaround where advanced linux expertise is required to do is not an option for many novice users.

I see this older other bug : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1634108
closed as fixed upstream.

I don't think that the best solution is to add kernel parameters.
The linux-image-unsigned-5.15.0-051500-generic_5.15.0-051500.202110312130_amd64.deb works, so that patch which is added into that one should come to an update ASAP.

Thank you!

[SZ (anari77)]

OK, I have tried stock ubuntu kernel version 5.15.0-37-generic
With /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="verbose intel_iommu=off"

firmware loads, wifi works.

[ 15.752699] iwlwifi 0000:3d:00.0: loaded firmware version 17.3216344376.0 7260-17.ucode op_mode iwlmvm

[ 16.104876] iwlwifi 0000:3d:00.0 wlp61s0: renamed from wlan0

So yes, this is a workaround.
Maybe this should be set up by default in the kernel somehow.
Thanks
