[SOLVED] Wi-Fi interface disappears after kernel update 7.0.13 - 7.1.2

I have updated kernel from 7.0.13 to 7.1.2 and Wi-Fi interface stopped appearing on the list of devices in iwctl. Basically it looks like this on kernel version 7.1.2:

$ iwctl
NetworkConfigurationEnabled: enabled
StateDirectory: /var/lib/iwd
Version: 3.12
[iwd]# device list
                                    Devices                                    
--------------------------------------------------------------------------------
  Name                  Address               Powered     Adapter     Mode      
--------------------------------------------------------------------------------

[iwd]#

The interface shows up on ip's output

$ ip a
....
wlan1: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
...

But nothing happens when I try to use 

ip link set wlan1 up

Further, no error messages are produced, neither when I look at journal or in the command line.

Dmesg for kernel vesion 7.0.13: here
Dmesg for kernel version 7.1.2: here

Many errors also show up after upgrading the kernel related iwlwifi module as seen from dmesg output.

$ lspci -k:
00:14.3 Network controller: Intel Corporation Arrow Lake CNVi WiFi
        DeviceName: Onboard - Ethernet
        Subsystem: Intel Corporation Device 6074
        Kernel driver in use: iwlwifi
        Kernel modules: iwlwifi

When downgrading to 7.0.13, interface shows up and works smoothly.
Edit: there is also a considerable time during start up on kernel 7.1.2 when the screen is completely black (5-10 seconds), showing "_" char in the corner. It does not happen on 7.0.13.

Could it be something on my side or is there somewhere I can report it? Thanks.

Re: [SOLVED] Wi-Fi interface disappears after kernel update 7.0.13 - 7.1.2

Might be related to https://bbs.archlinux.org/viewtopic.php?id=314132

But nothing happens when I try to use

The nic already *is* up, you lack a carrier ("cable")
=> https://wiki.archlinux.org/title/Iwd#Re … after_boot ?
Does it help to restart iwd?

Ideally please post your complete system journal for the boot: 

sudo journalctl -b | curl -s -H "Accept: application/json, */*" --upload-file - 'https://paste.c-net.org/'

so we get to see the kernel actions in relation to the userspace.

Re: [SOLVED] Wi-Fi interface disappears after kernel update 7.0.13 - 7.1.2

Apparently not, https://bbs.archlinux.org/viewtopic.php … 9#p2303739

@loqs, what makes me curious about the context - the chip might struggle early on but recover but then iwd no longer cares - or iwd is actually triggering this or it's caused by NMs mac spoofing or …
Also users tend to look at the wrong DOWN - https://wiki.archlinux.org/title/Networ … _interface wink

Re: [SOLVED] Wi-Fi interface disappears after kernel update 7.0.13 - 7.1.2

Agreed the context should clear this up.  My personal interpretation was the backtrace showing the last firmware reset failure was the driver giving up trying to get a response from the firmware and the device would then be stuck at least until the kernel module is reloaded.

But nothing happens when I try to use

The nic already *is* up, you lack a carrier ("cable")
=> https://wiki.archlinux.org/title/Iwd#Re … after_boot ?
Does it help to restart iwd?

Ideally please post your complete system journal for the boot: 

sudo journalctl -b | curl -s -H "Accept: application/json, */*" --upload-file - 'https://paste.c-net.org/'

so we get to see the kernel actions in relation to the userspace.

Thank you. Extending the unit with override.conf helped. Now device shows up and there is no errors in journal. I can further confirm that the issue starts with kernel version 7.0.14-arch1-1 as in the thread you referenced.

There are just a few questions to clarify:
- What is the difference between those two units? I have used the first one for override.conf.

$ sudo systemctl list-units --type=device | grep wlan
  sys-devices-pci0000:00-0000:00:14.3-net-wlan0.device                                                  loaded active plugged Arrow Lake CNVi WiFi
  sys-subsystem-net-devices-wlan0.device                                                                loaded active plugged Arrow Lake CNVi WiFi

- I have pointed out a black screen with considerable delay before SDDM shows up. With the fix, it made delay shorter, but it is still notable and does not happen on 7.0.13. Which logs would you recommend to attach for a new topic on this issue? It is not devastating, but still annoying.

Thanks again.

Re: [SOLVED] Wi-Fi interface disappears after kernel update 7.0.13 - 7.1.2

systemctl show sys-devices-pci0000:00-0000:00:14.3-net-wlan0.device sys-subsystem-net-devices-wlan0.device | grep Path

They're gonna be equivalent.

Please open a new thread and post the system journal, you can also check "systemd-analyze critical-chain" but it will at best tell "what", not "why" stalls.
