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,
g
