HW: Lenovo P15 Gen 2 (Intel)
openSUSE Slowroll
kernel: 6.11.5-1-default
KDE Plasma 6.1.5

HW: AMD Ryzen 3600
openSUSE Tumbleweed
kernel: 6.11.8 default
KDE Plasma 6.2.3 


Enabling preempt=full for the default kernel seems to cause repeating 1-2
seconds freezing periods. The frequency of freezing is a bit sporadic:
sometimes it may be freeze-free for an hour or two after a boot, sometimes it
starts freezing every ten seconds after a boot.

The issue seems hardware independent. I have it happening on a Lenovo P15 Gen2
Intel laptop, and on a AMD Ryzen at home.

During the break, keyboard inputs get duplicated, mouse freezes, and no UI
updates happening on Wayland.

I have not been able to point out any particular out of the system journal or
kernel logs.
