Hi,
On Bugzilla, danilrybakov249@gmail.com reported stable-specific, ACPI error regression that led into high CPU temperature [1]. He wrote:
Thanks for the report, and sorry for the trouble.
Overview:
After updating from lts v6.6.14-2 to lts v6.6.17-1 noticed high CPU temperature and lag. After running htop noticed that journald was using 30-60% of CPU. Afterwards, tried switching to stable, or lts v6.6.18-1, but encountered the same issue.
Running journalctl -f gives these lines over and over again:

My system info:
Laptop model: ASUS VivoBook D540NV-GQ065T OS: Arch Linux x86_64 Kernel: 6.6.14-2-lts WM: sway CPU: Intel Pentium N420 (4) @ 2.500GHz
I think this CPU is in Goldmont microarchitecture group. The group is handled in a bit unique way in drivers/platform/x86/p2sb.c. I guess the commit affected handling of P2SB resource on machines with that architecture.
GPU1: Intel Apollo Lake [HD Graphics 505] GPU2: NVIDIA GeForce 920MX
I've pinned down the commit after which the problem occurs:
847e1eb30e269a094da046c08273abe3f3361cf2 is the first bad commit commit 847e1eb30e269a094da046c08273abe3f3361cf2 Author: Shin'ichiro Kawasaki shinichiro.kawasaki@wdc.com Date: Mon Jan 8 15:20:58 2024 +0900

See Bugzilla for the full thread.
Thanks.
I do not have access to the hardware. As I commented on the bugzilla link above, I would like ask help for debug.
