Created attachment 156909 [details] logs from journalctl SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** The powerdevil process crashes at launch... and restart permanently. This generates gigabytes of logs. And I don"t know how to disable powerdevil completely (as I don't think I need it). I'm using KDE in a Tigervnc session, on an always-on server. Version is 5.27.2. X server is Xvnc (Tigervnc version) One of the main messages I received is : org.kde.powerdevil.chargethresholdhelper.getthreshold failed "Charge thresholds are not supported by the kernel for this hardware" Attached are my logs from journalctl

I see the same in a couple of 'just updated' F37 systems (KVM guests). A crash dump every 6 or so seconds. I'll see if I can compare details. Would be nice to know how to stop it :-) I haven't found "an obvious way" of disabling the service; nothing in the System Settings > Startup and Shutdown > Autostart or Background services. Seems to happen when I log in with X11, seems OK with Wayland Flagging Confirmed (although in my case not via VNC), I think as this is a seemingly indefinite crash loop it's worth a HI importance...

(In reply to tagwerk19 from comment #2) > ... a couple of 'just updated' F37 systems (KVM guests) ... Crashes (in X11) if the VM has the QXL video. Switch to Virtio and it goes away... I think the crashes are independent of the: ... org.kde.powerdevil.chargethresholdhelper.getthreshold failed "Charge thresholds are not supported by the kernel for this hardware" At least, I get that message whether starting with QXL or Virtio
Possibly should be reopened as it affects a different group of systems (X11 and not Wayland, there's a backtrace included in Bug 466808)...
I confirm that this is fixed with Plasma 5.27.3 Thank you very much!
Yay, thanks for following up!
