Perfomance problems with kernels newer than 5.10

Hello everyone,

I have actually had this problem since the 5.11 release, but I just kept using the LTS kernel because I didn't have time to investigate deep enough (or I was just lazy, but it couldn't possibly be true). It started on OpenSUSE Tumbleweed, but I've been on Arch since August, symptoms are exactly the same. Today the LTS kernel got updated to 5.15, I tried it out and the problem persists, so I guess it's too stupid to rollback and stop updating my kernel now.

Laptop: MouseComputer BC-MB1485UD11A-191
CPU: Intel Core i7-8565U
Audio server: Pulseaudio
Kernel: 5.15.14-1-lts

So, the problem. While running the 5.11+ kernel (5.15.14-1-lts at the moment), my system randomly gets very slow. Sometimes it happened right after boot, sometimes after wake from suspend, sometimes while I was working. But I think this actually got better with new updates, at least to the point when it no longer makes my laptop literally unusable for about 5-15 minutes. Before the touchpad was lagging, Wi-Fi was not connecting and so on.
What didn't get better is sound. My main examples are the YouTube videos and the Zoom calls, because they are usually long enough for this to occur. Sound suddenly starts lagging, freezing, "quacking" and such. With 5.11 there were errors like

CPU Bug - soft lockup...

while lagging and almost always on shutdown, but I don't see them now while my sound is chopping like crazy. In fact I see no errors in dmesg, except for the intel-undervolt triggered ones, and disabling it made no difference. It's just an informative message anyway.

[Wed Jan 12 17:16:43 2022] msr: Write to unrecognized MSR 0x610 by intel-undervolt (pid: 5280).
[Wed Jan 12 17:16:43 2022] msr: See https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/about for details.

So where should I look? My desktop PC with Intel Core i7-3770k runs the latest non-LTS kernel just fine, but my laptop can't work reliably on anything newer than 5.10. Please help me fix this.

Edit:
On second thought, I did find some segfaults in dmesg. Not sure they would tell anything, I didn't for example explicitly launch the gnome-documents at that time, but better than nothing I guess.
dmesg

Re: Perfomance problems with kernels newer than 5.10

1. why are you https://wiki.archlinux.org/title/Undervolting_CPU ?
What if you don't?
2. Do you https://wiki.archlinux.org/title/Microc … ly_loading ?
3. Does something charge CPU, RAM or IO (top/iotop)?
4. What cpu governor do you use and where's the frequency when it's fast/slow?
https://wiki.archlinux.org/title/CPU_fr … _governors
5. Please post a complete system journal

Edit: the dmesg is an excerpt only, but intel-undervolt is *very* suspicious here.

To actually have some battery life. Without it my laptop lived for about 2 hours under regular load (just multitasking, not rendering or compiling or something like that), which was unacceptable.

Yes.

By charge do you mean utilizes to 100%? No, nothing does, first thing I checked.

Powersave most of the time. 900-1900MHz usually, same on 5.10 with no problems. I am not talking about less than 60fps in Gnome animations, they were pretty slow on powersave forever, but sound was always ok on older kernels.

journalct

?
Trying to disable intel-undervolt was the second thing I tried after looking at the CPU load, and it only changed the chassis temperature.

sudo journalctl -b | curl -F 'f:1=<-' ix.io

if this has happened during the present boot, otherwise … "-b -1" for the previous boot etc.

curl gave no output, so mega again.

Quota, it's full of zeitgeist/tracker crashes and some game (debug?) logs.
Speaking of which - what if you remove/disable zeitgeist and tracker. It constantly crashing and restarting could very much cause cpu or io stalls.

Killed both zeitgeist and tracker, even uninstalled them. No changes.

Yay, I got it right now while rebooting.
soft lockup
Edit:
iptables are not to blame for sure, it's a different app each time. It's only consistent with audio server, everything else is at mercy of random.
Also it will just hang there until I hard reset the laptop.

Did that through grub config file and rebooted. Right now I need to charge my laptop, will test for some time.

Same thing, just a hotter laptop.

Hello,
Just found out there are separate packages tracker and tracker3. Tracker was harmless to remove, while half of my system depends on tracker 3. Stopped it for now, will look how it works out. But I'm pretty sure something will restart it sooner or later.

But battery life didn't seem to decrease significantly, so maybe I was just seeing things. I think that Baytrail might've used a different module to control CPU p-states, so maybe this parameter didn't do anything. I will check this when my workday is over.

Apparently GDM now crashes each time I use touchscreen input in Firefox.

Re: Perfomance problems with kernels newer than 5.10

http://0x0.st/oHOi.log

No touchpad reset now, and only Firefox crashed. Just in the middle of YouTube playback, which stutters miserably as a reminder.
Did't touch the screen or the touchpad, it just hangs and revives from time to time, sometime tabs crash, sometimes Firefox dies, rarely the whole gnome-session (I though about GDM because it drops me to an unresponsive TTY screen with a blinking cursor, CTRL+ALT+Fx does nothing, and in a minute or two GDM appears). Some actions like touchscreen scrolling seem to trigger this, but it will happen with no input from my side eventually.

Re: Perfomance problems with kernels newer than 5.10

FF dies somewhere in libxul (it's own workhorse library)
Do you have similar problems w/ chromium?
And if the issues are limited to the browser: what's the output of "about:gpu"?

Hmm. That address doesn’t look right.

Please check that the URL is correct and try again.

Re: Perfomance problems with kernels newer than 5.10

What is the output of

$ pacman -Qs xf86

?

I want to remind you that with every single thing staying the same, only changing the running kernel from 5.10.x to anything newer for a past year my system changes from running perfectly fine to a lagging mess. I think almost every package related to graphic rendering and sound got updated in that year, and every version/configuration worked with kernel 5.10. On OpenSUSE and on Arch. Everything crashes with 5.11, 5.12 ... 5.16. On OpenSUSE and on Arch. Doesn't matter the driver. Doesn't matter the distribution. The only single trigger is the kernel.

Re: Perfomance problems with kernels newer than 5.10

I've installed the Zen kernel with little hope, but seems like it actually worked. Will need to test a couple of days/boots more, but there are no lags at all right now.
I guess next is inspecting the diff between regular/LTS and Zen, and maybe testing to find problematic option(s). But I'm not really sure when I will be able to spend at least a day compiling and booting kernels.

Re: Perfomance problems with kernels newer than 5.10

There have been many reports where changes in the i915 kernel module gave problems with xf86-video-intel , but not when using modesetting driver.

For testing purposes you could try removing xf86-video-intel.

Well, no, it just lags faster, if that makes sense. And rarer. But it does.
Firefox is able to handle touch input, but YouTube tabs occasionally freeze (for a forth of a second instead of 5 seconds) and crashed couple of times today. Whet I was rebooting, I got the same SOFT LOCKUP message, but for about 10 seconds instead of 5 minutes. And so on. This makes the experience tolerable, but doesn't solve the problem as I originally thought. At least I am able to use my laptop almost normally now.

Will try removing the intel xorg driver.

No change. Also it occurs both before GDM starts and after it's stopped, and I use wayland in both GDM and Gnome-session (not sure if xorg drivers are even used in this scenario).
