If the problem was a kernel update, try switching to the LTS kernel.
If the problem was mesa, you could try mesa-git aur package.
If still neither of those 2 options solve your problem; your memory could be fcked, so time to try running memtest (this is time consuming, but if it confirms your memory is screwed, you can try replacing ur ram).
This happened to me three or four times, once I opened GIMP, and the other times while watching a video on YouTube, the device freezes and the sound remains for a few seconds and then cuts off and nothing responds until I turn off the device.
Update: I tried Fedora with kernel 6.12.4, and after hours it happened again. I think it has something to do with this version of the kernel, so I installed the LTS version on Arch, waiting for version 6.12.5 to be released in the official repositories.
BTW, I tried all the parameters suggested here for the kernel to no avail, and my BIOS version is up to the latest version.
Is there anything new about the problem? Is it still going on with you? I can’t use my device, and I’m thinking of installing Windows even though I don’t like it.
I ended up buying a new laptop (Thinkpad T14s just in case). I wanted to make the upgrade since a while but also this freezes issue didn’t let me work with the Ideapad, so I was obliged to do it.
So, I didn’t use it anymore and in the end I ended up selling it with Windows 10 (FYI, I could run a game withouth freezes).
