### Summary

Fedora 42 kernel `6.16.9-200.fc42.x86_64` causes black screen on boot (GDM repeatedly crashes) with Intel Lunar Lake integrated graphics (`xe` driver). Previous kernel `6.16.8-200.fc42.x86_64` works normally.

### Hardware

* Laptop: **Lenovo ThinkPad X9-15 Gen 1**
* GPU: **Intel Arc Graphics 130V / 140V (Lunar Lake, PCI ID 00:02.0)**

### Software

* Fedora Workstation 42 (fully updated)
* Display manager: **GDM (Wayland)**
* Kernel packages installed:

  ```
  kernel-6.14.0-63.fc42.x86_64
  kernel-6.16.8-200.fc42.x86_64  <-- working
  kernel-6.16.9-200.fc42.x86_64  <-- failing
  ```
* Firmware packages installed:

  ```
  nvidia-gpu-firmware-20250917-2.fc42.noarch
  intel-gpu-firmware (latest available from Fedora repos)
  ```

### Steps to Reproduce

1. Boot into kernel `6.16.9-200.fc42.x86_64` from GRUB.
2. The system begins booting (Lenovo logo and Fedora boot splash appear).
3. Screen goes black and never reaches GNOME login screen.

### Actual Results

* `gdm.service` repeatedly crashes and restarts.
* Black screen persists, system is otherwise running (can switch to VT with `Ctrl+Alt+F3`).
* Journal shows `gdm` segfaults in `libglib-2.0.so` after GPU init.

Relevant logs:

```
Oct 06 10:43:36 fedora gdm.service: Main process exited, code=dumped, status=5/TRAP
Oct 06 10:43:37 fedora abrt-notification[1696]: Process 1232 (gdm) crashed in get_fallback_session_name()
Oct 06 10:43:25 fedora kernel: traps: gdm[1480] trap int3 ip:... in libglib-2.0.so
```

### Expected Results

* System should boot into GNOME login screen (as it does on kernel `6.16.8-200.fc42.x86_64`).

### Workarounds

* Booting into previous kernel (`6.16.8-200.fc42.x86_64`) works fine.
* Booting the failing kernel with `nomodeset` avoids the crash but disables GPU acceleration.

### Additional Info

* Logs from failing boot attached (journalctl output).
* This appears to be a regression introduced between 6.16.8 and 6.16.9 in the Intel `xe` driver stack.
