[bug] NVidia GSP randomly crashes Wayland session

Hello!

System report: https://paste.cachyos.org/p/46829b6.log

After last kernel+nvidia driver upgrade [1], my system randomly crashes. The previous boot log contains the following entries:

```
[root@miriam ~]# journalctl --utc --boot=-1 | grep NVRM
abr 08 12:39:04 miriam kernel: NVRM: loading NVIDIA UNIX Open Kernel Module for x86_64 570.133.07 Release Build (notroot@34a3ffbed8a3) Fri Mar 28 11:18:11 UTC 2025
abr 08 12:39:05 miriam kernel: NVRM: _intrInitRegistryOverrides: NV_REG_STR_RM_INTR_LOCKING_MODE was set to: 0x1
abr 08 18:10:23 miriam kernel: NVRM: nvAssertFailedNoLog: Assertion failed: CliGetEventInfo(rpc_params->hClient, rpc_params->hEvent, &pEvent) @ kernel_gsp.c:467
abr 08 18:10:23 miriam kernel: NVRM: _kgspProcessRpcEvent: Failed to process received event 0x1003 (POST_EVENT) from GPU0: status=0x57
```

First 2 lines is normal boot. 2 last lines happens in same moment screen freezes. Applications keep running (Eg. Music keeps playing and being controlled by Bluetooth controls), but image got entirelly frozen. Also I was unable to access framebuffer terminals.

Behavior is the same reported at https://forums.developer.nvidia.com/t/2nd-monitor-frozen-recent-freezing/325588 nvidia forum post. A relevant information: This post says about 2nd monitor and I do not have a second monitor plugged right now, but I have a displaylink monitor that I use sometimes, so evdi and displaylink daemon are loaded. I tried now to disable it.

Since this may be GSP related issue, I've disabled GSP:

```
[root@miriam ~]# cat /etc/modprobe.d/nvidia-gsp.conf
options nvidia NVreg_EnableGpuFirmware=0
```

And my system is running (but not sure about stability since I just restarted it).

That said and considering CachyOS tells this option is not appliable while using open source drivers (https://wiki.cachyos.org/configuration/general_system_tweaks/#nvidia-gsp-firmware), I do not know how to proceed to troubleshoot it. Can CachyOS Dev team help-me to find out what happened?

Thanks!
