Have you tried the mainline kernel as suggested on your bug report?

Hi, I am not sure what it means and what to do.
Should I upgrade kernell version?

Yes. That's what it means

Thank you for your response. I’m currently on version 6.8.0-45-generic, but according to [Phoronix](https://www.phoronix.com/news/Linux-6.12-rc7-Released), version 6.12 is expected to be released this Sunday, November 17. It does seem a bit intimidating, so I’ll do some research on safe upgrade methods to avoid any issues with PC access.

I’ll look into it, but based on [Ostechnix’s article](https://ostechnix.com/linux-kernel-6-12-rc7-released/), I think it might be safer for me to wait for the final release. Since I primarily use Ubuntu and have never attempted an upgrade like this, I’m a bit concerned about the possibility of breaking my system.

sudo add-apt-repository ppa:cappelikan/ppa
sudo apt update
sudo apt install mainline

Should install a nice GUI you can use. Here is a guide (scroll down to after the commands above)
