Thinkpad L390, i5-8265u, UHD 620, Fedora Linux 44

System completely hangs a few seconds after hotplugging. Nothing is responsive. TTY doesn't open. After unplugging the monitor the hang still happens. It got to the point where it froze on SDDM. GRUB rescue doesn't open either. Only a force restart works. Liveboot surprisingly works. The only fix I did was reinstalling the system.

At first I thought this was a DE specific error, but this happened both on Niri and Plasma. Checking journalctl doesn't show anything relevant (perhaps it got killed before logging anything?) It wasn't a thermal issue either (stable 50°).

I landed on the assumption that this could be a drivers bug at this point. I also see that people who has a similar problem on the same iGPU I use fixed it by disabling PSR. I haven't tested kernel params yet, need to know if anyone has a similar problem and a fix for it.
