Dear kernel team,

I've seen this issue with 6.18 too, and I can confirm it's not happening
with 6.12.74-2 (and same firmware-atheros 20260110-1) but I still need
to do a formal git bisect.  I am not sure either this is a
firmware problem.

After resuming from suspend, wifi conections get flaky, with different
symptoms: mainly my machine is not able to associate to a network, or
when associates, wifi stops working after some minutes (while remain
'associated').

This is dmesg | grep ath11k_pci:

Please, let me know what other information would be useful (other than
the git bisect).

(I'm setting severity to normal, but when moving with my laptop this
issue becomes a pain for me.)

A quick follow up (that was unsuccessfully sent yesterday):

After sending the report, my wifi network (Network A - "Starbucks")
stopped working. With "stopped working" I mean that my machine lost the
association with the AP. I made several tries to associate to the same
network again, without success. This I what I could see on dmesg:

I switched to another wifi network (Network B) that my machine get
associated to, but the network wasn't actually usable (although, it was
usable from another device).  My machine got an IPv4 address and route,
but it was not able to reach the outside network.

FWIW, this is from network A, after getting associated again, but
networking was not usable either:

While the issue hit again (with 6.19.8+deb14-amd64), I'm still not sure
when it happens, so I cannot reproduce it systematically.  That said,
I'm pretty sure this is something that didn't happen with 6.12 or
earlier kernels. Providing more info could take me some time…

Thanks for the notice. I will adapt my patch to remove the conflict with yours.

I've also been hit by a similar annoying wifi randomly dying issue that
you describe [deb#1132343].  With the patch that I attached applied to
7.0.0, my P14s G3 AMD laptop has been running for more that 3 days, with
several suspends / weak ups, either with power connected or
disconnected.  And I haven't encountered that problem since it booted so
I concluded that the patch fixed it.  But chances are that I am wrong.

[deb#1132343] https://bugs.debian.org/1132343

The latest bad version I tested where the wifi died was 6.9.11.  I plan
test the patch on top of it.

Feel free to just merge yours and I'll withdraw mine. I'm regression
testing the WiFi disconnect issue I'm encountering, so I'll just focus on
that. In the meantime this seems righteous.

6.9 or 6.19? My issue started between 6.16.10 and 6.17.4.

Thanks, I've just sent an updated version

6.19, sorry.  And I confirm it is still present in 7.0.3. But my P14s
Gen3  machine has been running on a 7.0.3 patched with
https://lore.kernel.org/ath11k/20260423211458.458911-1-santiagorr@riseup.net/
for more than two days, with several suspends and no wifi issues.

However, from your comment at
https://lore.kernel.org/all/CAOPSVF04q6uvVdq8GTRLHBrVMdpt9=o9wVcFMc6f-yhmSBcZqQ@mail.gmail.com/,
I read that you are concluding that the culprit for the dying wifi is
rather 79266fd78df1 ("wifi: ath11k: HAL SRNG: don't deinitialize and
re-initialize again").
Could you please confirm that you have been able to reproduce the wifi
randomly dying issue with kernel patched with
https://lore.kernel.org/all/20260330-p14s-pm-quirk-v2-1-ef18ce07996b@gmail.com/?

Hi Santiago,

That was
https://git.kernel.org/linus/f51e4b3b5574ad8cb5b16b11f8a1452147ece87a
which was backported to 7.0.11 as well.

I'm closing thus the bug with 7.0.12-1 including as first version that
change as well.

Can you please reopen if you still experience the problem please?

Regards,
Salvatore

My laptop currently has a 2-day uptime, with some suspends+resumes, and
running:

While my laptop's wifi stopped working (and had to unbind / bind the
device to fix it), I confirmed that other devices on the same network
were working correctly.

Kyle, have you observed any regression after your patch was included?
And thanks for your work, BTW.

Do you see the same log entries in journalctl when the issue occurs? What
are the recovery steps you're using to get it working again?

Were there any other logs leading up to to the DEAUTH_LEAVING? That looks a
lot like a normal disconnection, my typical repro looked more like:

wlp2s0: deauthenticated from <AP> (Reason: 6=CLASS2_FRAME_FROM_NONAUTH_STA)

I found `journalctl` more useful because it showed the other services as
well, like in [1]. When in this state, I could connect to the hotspot on my
phone, but in a couple of cases, this crashed the Wi-Fi card's firmware. I
didn't know about bind/unbind, I would just unload/reload the ath11k_pci
kernel module and then it would connect properly.
