Powerdevil seemingly cannot put system to sleep correctly

General system Kernel, boot, graphics & hardware

Hello! I had all methods of sleeping working completely fine (suspend/hibernate/etc.) on my laptop for about a week, but after an update yesterday (10-24-2025), it seems that every action powerdevil (KDE) attempts to make, fails.

When powerdevil attempts to hibernate, the system instead seems to suspend, and the journal says Failed to put system to sleep. System resumed again: Device or resource busy and only sometimes says Freezing remaining freezable tasks aborted after 0.834 seconds (1 tasks refusing to freeze wq_busy=0)

When powerdevil tries to suspend, the journal says PM: Some devices failed to suspend, or early wake event detected

However, running systemctl suspend or systemctl hibernate seems to work perfectly, as well as clicking the buttons for the actions in KDE itself.

Anyone know how I could find the device apparently blocking the sleeping and fix it?

Note: qdbus org.freedesktop.PowerManagement /org/freedesktop/PowerManagement Hibernate and qdbus org.freedesktop.PowerManagement /org/freedesktop/PowerManagement Suspend also do not work. I am also on Wayland.

I’ve temporarily fixed the problem with swayidle, but I’m hoping that a kernel update will eventually solve the problem.

nano ~/.config/autostart/swayidle-hibernate.desktop
