What were you trying to do that didn't work?

After upgrading from RHEL 10.0 to RHEL 10.1, the system freezes before reaching the GDM graphical login screen. Boot completes, but the graphics stack fails to initialize.

What is the impact of this issue to you?

The system becomes unusable in graphical mode. The customer can only log in via TTY (multi-user.target). This affects usability and prevents running graphical workloads.

Please provide the package NVR for which the bug is seen:

Kernel: kernel-6.12.0-124.8.1.el10_1.x86_64

How reproducible is this bug?:

Always occurs on this hardware (Lenovo M910q with Intel HD 530 GPU) after updating to RHEL 10.1.

Steps to reproduce

1. Install and run RHEL 10.0 on Lenovo M910q (Intel HD 530 GPU).

1. Upgrade to RHEL 10.1.

1. Reboot system.

1. System freezes right before GDM loads.

1. Switching to multi-user.target allows login via TTY.

1. Starting GDM manually (systemctl start gdm) triggers an immediate freeze.

Additional observations from customer:

• Wayland/Xorg changes do not help.

• vainfo fails.

• Installing libva-intel-hybrid-driver from EPEL doesn’t resolve the issue.

• Issue does not occur on another machine with Intel HD 630 GPU using the same SSD/system.

Expected results

The system should boot normally into the GDM graphical login screen, as it did on RHEL 10.0.

Actual results

The system freezes or displays a black screen with a cursor just before GDM appears. Only TTY login works.
