[Bug 2159937] [NEW] ASUS X411UA hard-freezes after GDM blanks display on i915

Public bug reported: Hardware: - ASUS VivoBook S X411UA - Intel Core i7-8550U - Intel UHD Graphics 620, PCI ID 8086:5917, i915 - BIOS X411UA.310 - Internal 1920×1080 display Software: - Ubuntu 26.04 - Kernel 7.0.0-27-generic - GNOME/GDM using Wayland Steps to reproduce: 1. Boot to the GDM login screen. 2. Leave the machine idle until the display blanks. 3. The machine subsequently becomes completely unresponsive and requires a hard power-off. Moving the cursor delays both display blanking and the freeze. The issue reproduced repeatedly. The journal ends abruptly without a clean shutdown, OOM, storage, or thermal error. Before one freeze, the kernel repeatedly reported: workqueue: output_poll_execute hogged CPU workqueue: i915_hpd_poll_init_work [i915] hogged CPU Testing: - i915.enable_psr=0 alone did not fix the problem. - i915.enable_psr=0 i915.enable_dc=0 has remained stable during stress testing and display blanking so far. Expected result: The display blanks and wakes normally without affecting the system. Actual result: Display blanking leads to a complete system freeze.
