I'm going to ignore the Xwayland crash because that will never freeze the system, it can only break legacy apps.
The main issue here still seems to be related to the Nvidia kernel driver. It looks like it's complaining about sending commands to PCI:0000:05:00 a lot. I also wonder if your GPU setup is confusing one of the drivers since you have Nvidia as primary and AMDGPU as secondary. It's possible the whole issue might go away if you disabled AMD graphics in the BIOS. ** Changed in: nvidia-graphics-drivers-570 (Ubuntu) Status: Incomplete => New ** Tags added: amdgpu hybrid multigpu -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2115193 Title: System freezes randomly on Ubuntu 25.04 Wayland with nvidia- driver-570-open To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-570/+bug/2115193/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
