I have a laptop with AMD processor and AMD video card. Past times, my laptop constantly freezes and I would wait to ending this for a while. ( approximately 10 mins) I'm a KDE user and it mostly happens while using Qt applications. (E.g Spectacle) I was looking for a solution for a long time and I asked this to OpenSUSE's Telegram group. They said it caused by ACPI and recommend me to switch off the ACPI by boot parameteres, I didn't do it and I get used to use my system by this way. However when I block the graphical switch (with "echo 1 | tee /sys/bus/pci/devices/0000\:01\:00.0/remove"), this problem goes away and I understand it relates with graphical switch. Then I looked at journalctl and I see some weird AMDGPU output when system freezes.
