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:

	Kernel driver in use: ath11k_pci
	Kernel modules: 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.)

Cheers,
