Last night, I updated my Arch Linux machine in the usual fashion which included an update of the powerdevil package to version 5.27.10-2, then proceeded to power off for the night. Upon booting up this morning, I quickly noticed that the KDE crash report tray widget was repeatedly, and rather quickly, appearing and disappearing. From what I can tell, /usr/lib/org_kde_powerdevil is starting up, crashing, and attempting to start up again, causing strain on the system. Attempting to use the Power Management menus in the systems UI confirms that it is not loaded. The KDE Crash Handler also is closing and reopening quickly, making it difficult to get any diagnostic information through it. I've included my entire "journalctl -b 0" output in the hopes that it's useful. I can attempt to get better dumps/stack traces if someone can point me to them. I typically use Wayland, but did switch to X11 as a test and was still seeing the same issue. My only other idea is to switch to an LTS kernel, which I will do after this and report back. I have not installed any new hardware in some time. STEPS TO REPRODUCE 1. Boot up the system OBSERVED RESULT Powerdevil is stuck in an infinite boot loop EXPECTED RESULT Powerdevil will start up normally SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux KDE Plasma Wayland - Kernel 6.7.0-arch3-1 KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.114.0 Qt Version: 5.15.12

I've had to switch to a different DE for the time being, but I can attempt to assist in debugging if need be.

This appears to be related to the recent release of ddcutil 2.1.0, not a kernel change, and is similar to https://bugs.kde.org/show_bug.cgi?id=476375 -- downgrading to ddcutil 2.0.0 is a temporary fix until this is addressed. For Arch, "sudo pacman -U https://archive.archlinux.org/packages/d/ddcutil/ddcutil-2.0.0-1-x86_64.pkg.tar.zst" will take you back.
