Anyone experiencing slowdowns with kernel 6.10.10, or is it just me? After a few minutes of uptime, long enough for the system to go to sleep, when I wake it up again it’s unusably slow. The GUI is lagging, switching to a tty is still slow. top reports heavy CPU usage of one kworker/##:#-events thread or another, it’s always one at a time but it doesn’t stay the same one. I’m not sure how to troubleshoot this. I have resolved the issue for now by booting to the 6.10.9 kernel. Thought I’d write about it here in case others experience the same issue, if it’s a problem with this kernel version.
I have VirtualBox host kernel modules installed, possibly other third-party kernel modules I can’t remember, maybe something needs recompiling?
I have been experiencing the same issue and I’m usually forced to reboot the laptop. I usually only have Firefox (system package), Thunderbird (Flatpak), VS Code (official package), and several alacritty (manually built) windows open. Sometimes also when browsing local and network shares in Dolphin.
It seems to happen more often when trying to video playing on a web page or loading web app, but not always.
Details from About this System:
Operating System: Fedora Linux 40
KDE Plasma Version: 6.1.5
KDE Frameworks Version: 6.6.0
Qt Version: 6.7.2
Kernel Version: 6.10.10-200.fc40.x86_64 (64-bit)
Graphics Platform: Wayland
That’d be consistent with me, I’m on a AMD Ryzen 7 PRO 7840U CPU with Radeon 780M Graphics, we have nearly identical platforms. Saw a 6.10.11 kernel just dropped, I’ll try that next time I reboot.
I’m having the same issue as @aescwine described. And I also confirm what @theqlp described: It seems to happen more often when trying to video playing on a web page or loading web app, but not always.
My system:
OS: Fedora release 40
Desktop: GNOME 46.5
CPU: AMD Ryzen 7 6800 HS with AMD ATI Radeon 680M Graphics
GPU: NVIDIA GeForce RTX 3050
Memory: 32GB
I experience the issue with 6.10.10 and 6.10.11. The temporal solution for me was also revert back to 6.10.9
I tried out 6.10.12 (from the updates-testing repo) and experience the same issue about 5 minutes after waking up my laptop and only having a couple of tabs open in Firefox. I’m now back to 6.10.9. sigh
I use an AMD CPU, AMD Ryzen 7 6800H with AMD Radeon 680M graphics. I have an Nvidia card, but am not using the Nvidia drivers.
I also use KDE, kernel 6.10.10 and I also have several kworker threads visible in top, but here the one with the highest CPU use shows only 0.3%.
System in total is using around 5% and feels normal, no hickups, no waiting, just a responsive system.
No idea if this has something to do with it, I am Fedora Kinoite 40, the immutable version.
It could be certain interactions with appilcations and the AMD GPU drivers, since the issue is also reported with Arch Linux. I’ve seen it happen with both the Fedora-packaged Firefox + RPM Fusion Mesa drivers for video encoding/decoding offloading and the Flatpak version of Firefox + same drivers.
