Created attachment 286159 [details] "journalctl --user" log After upgrading my kernel (on ArchLinux) from 4.11 to 5.4, wpa_supplicant and iwd no longer works due to a problem with the iwlwifi kernel driver. My linux-firmware version : 20191022.2b016af-3 Does anyone have a solution ? I'm not an expert in kernel debugging.
I'm sorry, it's from 5.3.13 to 5.4.1
@Eliott this seems to be related: https://bugs.archlinux.org/task/64703 I'm having similar issues with my 9462 card, also not working after the upgrade to 5.4.1. I'll try to post a dmesg from the latest kernel and LTS today.
I actually have a 9560, it's just reported to be a 9462 by lspci. iwlwifi: [ 46.839888] iwlwifi 0000:00:14.3: Detected Intel(R) Wireless-AC 9560 160MHz, REV=0x354 I added dmesg and lspci logs in the arch linux bug tracker thread I linked above.
same here: 5.3.13 works but 5.4.[12] doesn't. dmesg (under 5.3.13) says I have iwlwifi 0000:00:0c.0: Detected Intel(R) Dual Band Wireless AC 9462, REV=0x318
Same problem has happened on Linux 5.5.0-RC3 kernel and all Linux 5.4.x versions. iwlwifi 0000:00:14.3: Detected Intel(R) Dual Band Wireless AC 9560, REV=0x318
Created attachment 286507 [details] dmesg log on kernel 5.5.0-RC3
Same issue has happens after upgrade from 5.3.13.1-1 to 5.4.7 00:14.3 Network controller [0280]: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] [8086:9df0] (rev 30)
I tried to watch devices via 'iw dev' and 'ip link', and one of twos state was happens: 1) There are no wireless devices (only loopback at `ip link`) 2) Wireless device has been find, but interface is down and `ip link set wlp0s20f3 up` -> returns "rtnetlink answers input/output error"

This comment https://bugs.archlinux.org/task/64703#comment184511 Suggests bisect showing the regression is due to commit 06eb547c4ae4 ("iwlwifi: mvm: fix scan config command size"). Someone with the actual hardware should confirm/deny that. And also, this bug (bug 205749) should have complete dmesg attached; as well as 'lscpi -vvnn' attached. Snipped reports are generally less useful.

For whatever reason, it's not in 5.5rc5, nor in next, which would explain why it's not in 5.4.11.
I own effected hardware. I've added the output of "journalctl --no-hostname -k" and "lspci -vvnn" from kernel 5.5.0rc5.

Have had this device broken in every 5.4 kernel tried from 5.4.7 through 5.4.13. Have not tried any 5.5. Intel 9462 wifi adapter in an Intel NUC7PJYH. Is there a plan to get this issue assigned and the fix pulled in to mainline?

Noticed fix has also now been backported to 5.4.16, per https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.16
So can this ticket be closed out?
Also are the Intel devs still active? I hate to bump this thread but I filed a bug the other week and haven't gotten a response
