Bug ID: 457793
Summary: Powerdevil restart loop on startup on kernels 5.18+
Product: Powerdevil
Version: 5.25.4
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: leob9...@gmail.com
CC: m...@ratijas.tk
Target Milestone: ---

journalctl --grep "powerdevil" output from a kernel 5.18.x boot
SUMMARY
Ever since kernel 5.18 came out Plasma has started hanging on startup, not
showing panels, slowing down performance (wifi and bluetooth fail to work), and
causing an infinite loop at shutdown (stop job running forever). These problems
do not occur when booting an LTS kernel (5.15.x) or when downgrading to the
last version of kernel 5.17.
Laptop Specs are as follows:
Model: ASUS K501UX
CPU: Intel core i7-6500U
GPU: NVIDIA GeForce GTX950M
STEPS TO REPRODUCE
1. Booting the system on kernels 5.18+
OBSERVED RESULT
Plasma hangs on startup, with panels not showing and most functionality (e.g.
network and bluetooth) unavailable. Performance is also greatly reduced. Trying
to power off the system results in an infinite stop job running, requiring to
force shutdown by keeping the power button pressed.
EXPECTED RESULT
Normal startup of a Plasma session, I guess.
SOFTWARE/OS VERSIONS
Linux: 5.18+ (EndeavourOS)
KDE Plasma Version: 5.24.x - 5.25.x
Qt version: 5.15.5
KDE Frameworks version: 5.96.0
ADDITIONAL INFORMATION
It is worth mentioning that if I boot into kernel 5.18.x AFTER a session on
kernel 5.15.x, this problem does not occur; however it starts happening again
when I boot into 5.18.x more than once consecutively. Maybe powerdevil is
looking for some information from the previous session that for some reason is
not generated when running from kernel 5.18?
The outputs of journalctl --grep powerdevil for a "hanging" (kernel 5.18.x)
session and a "healthy" (kernel 5.15.x) session have been attached to this bug
report.
