Subject: [bug] mhi: ath11k: resume after hibernation is not working
Date: Fri, 22 Sep 2023 14:00:16 +0200 [thread overview]
Message-ID: <20230922120040.15460-1-jtornosm@redhat.com> (raw)
Hello,
We have several machines with QCNFA765 wireless card (WCN6856) and with
the same behavior: although hibernation seems to work, post resume is not
working due to the wireless card (if the wireless card is disabled or ath11k
driver is blacklisted, everything is working).
After hibernation, when we resume (power on), we get the following related
logs:
...

Could you help me to fix this?
Why is M3->M0 transition not working? Could it be an issue with the firmware?
Thanks
Best regards
José Ignacio
