Random hang/crash (Ryzen 4700U)
With a 5120x1440@120Hz monitor connected through a USB C -> DisplayPort cable, my HP Envy x360 randomly hangs - sometimes after a few hours, sometimes after minutes, once today only a few seconds after logging in. When that happens, both the internal and external displays turn off and on again in a cycle, being in each state for a few seconds, and the content of the screen never changes. The device seems to still be responsive in other ways, but when I try to shut it down through KDE connect or ssh, it stops being reachable but it never actually shuts down until I kill the power.
This has happened on Manjaro and on Fedora, with kernels 6.2 and 6.3 tested so far. I can test other kernels if that's useful, but as it can take multiple hours of using the laptop before the hang happens, it may take a while.
