Hi all.
After a resume I get the following error:

This is a stock Ubuntu Jammy lowlatency kernel (with Nvidia drivers).
I would be happy to provide all the needed information to resolve this.
I also want to note that the device is running quite unstable (lots of
deauthenticating, network lost, etc...).
Regards,

Contact Ubuntu. The rule for upstream is if you load out of tree drivers
than that kernel is unsupported.

Dear Stephen,

I compiled a stock 5.17.5 kernel from git.kernel.org, installed
without kernel headers (forcing dkms to not build proprietary drivers)
and get the following errors *at boot time* (not suspend/resume):

I sent the first email because I suspected that the above (locking?)
problem was totally unrelated to the GPU driver.
I hope that this is more helpful.

Going through the source it seems that the concerned field is
is_valid_ack_signal which is never set by mt76, only by ath10k.

Mmm, I got something similar but I upgraded and now I get:
