The wifi seems to work fine, so do it is not a blocker, but probably some kind of race in shutdown the wifi when plugged in the lenovo dock station

Hi,

I used Wi-Fi for some time then disabled Wi-Fi with NetworkManager.

Here is my Wi-Fi adapter:

Sorry for the delay in handling this.

Now 5.2 is not maintained anymore, can you please test with v5.4.3 (latest stable) or v5.3.16, whichever is easier for you?

Thanks for testing on the new kernel and adding new logs. We'll take a look at it now.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[You-Sheng Yang (vicamo)]

Firmware iwlwifi-9000-pu-b0-jf-b0-*.ucode, version core45-152, is already up to date.

Please try following options separately:

1. mainline kernel: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.6-rc2/

   While you have also out-of-tree nvidia driver installed, you'll need *_all.deb, *-generic_* four packages. nvidia may fail to build against newest mainline kernel, so you may also need special care to that.

2. backport-iwlwifi-dkms: https://launchpad.net/ubuntu/+archive/primary/+files/backport-iwlwifi-dkms_8324-0ubuntu1_all.deb

can you update to the latest Eoan kernel and report if such a bug still exist?

Hi,

What WIFI FW are you using?
dmesg should have it on load.
can you take latest from here: https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
?
and update if still reproduces?

> can you take latest [firmware] and update if still reproduces?

This bug is quite old, and I do not see this exact WARNING anymore.

What I see on my system today is the following error. I am going to open another bug report...

Hi,
1. The sha1 you added doesn't tell the FW file. The full dmesg does show, but I can't find it.
2. This is a different bug. we have a fix for it on FW API 69 which will be part of 5.17.

If this bug doesn't repro please close it.
