Source: linux
Version: 6.19.8-1
Severity: normal

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:

I don't have core dumps enable right now, but will try to get one with
next try.

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:

Assuming this is reproducible: Does it help to reload the driver? E.g.
doing as root:

	cd /sys/bus/pci/drivers/ath11k_pci
	echo 0000:02:00.0 > unbind
	echo 0000:02:00.0 > bind

Best regards
Uwe

That helped, thanks.

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…
