CPU tainted in dmesg since 5.11

Created attachment 848532 [details] dmesg output Hello, Tumbleweed 20210417 Kernel 5.11.12-1.1 (any 5.11.* in fact) Every time I boot with a 5.11 kernel, I experience a lot of problems. Touchpad is lagging, Wi-Fi not connecting and so on. But everything is fine on 5.10.16-1.3. Dmesg is full of this: [506.529437] CPU: 4 PID: 7993 Comm: kworker/4:0 Tainted: G S W 5.11.12-1-default #1 openSUSE Tumbleweed More in the attached file.
The taint flag is likely a red herring. You might have done some MSR write from user-space? That would taint the kernel ('S' flag).
You mean like described in this issue: https://github.com/kitsunyan/intel-undervolt/issues/55 ? This seems to be my case as I do use that project, but that never caused severe perfomance issues (making PC unusable) I am experiencing on 5.11.
Could you attach fill dmesg? As the excerpt you provided is very past the original issue.

Sorry for the lack of response, it's been a crunchy time. Seems like everything is fine on 5.12 for a couple of days though.
And now with the 5.12.3-1-default kernel it's really bad again. Touchpad is unusable, the whole system is stuttering every few seconds. Attaching the full dmesg output.

Could you check with the kernel package in OBS Kernel:stable repo? http://download.opensuse.org/repositories/Kernel:/stable/standard/
So far way smoother on startup and in general. Mouse cursor still lags occasionally, but overall a lot better than mainline kernel. I will add more feedback after a couple days of running and sleeping.
Experienced a very strange behaviour on 5.12.4-4.g2d71c6c-default just now. Booted up, logged into Gnome, successfully launched terminal, launched my standard set of work software (Brave, Telegram, Discord, QOwnNotes, Evolution, 1Password, VSCode, VM Manager) and nothing of it started. Waited for about 2 minutes, still none of GUI apps I launched have started. Terminal commands didn't run either, everything just sort of freezed on the inside. But Gnome Shell seemed to be ok, I was able to type and click stuff. No idea what happened, and no logs because of dead terminal. Rebooted again and everything is fine.

I now get errors like in the photo I just attached every shutdown. It takes ages to poweroff. After boot, it feels like I randomly get either a borderline usable system or a complete mess. It can also change at any moment (sometime Wi-Fi just stops working. It is shown as active, but nothing from LAN or internet loads, it doesn't react to me trying to switch Wi-Fi off. Not to mention touchpad, it might lag a bit or the cursor can just freeze at one position and not react to either touches or clicks for several minutes.
Still occurs on 5.13.1-4.g72aabc2-default If there are any other logs needed - please tell me where and how to find them.
Please give the log from the latest state.
Also check whether you get the same problem even after disabling intel-undervolt, too. It's the only suspicious piece, so far.

Which problem are you referring to...? I see no error there.
