**Me too + working workaround — ASUS ROG Zephyrus G14 (GA401QM), Linux Mint 22.3 / Ubuntu 24.04 base**
Same regression here, confirmed boundary 7.0.0-27 (good) → 7.0.0-28 (bad). Hardware: ASUS ROG Zephyrus G14 GA401QM, AMD Renoir iGPU (amdgpu) + NVIDIA RTX 3060 dGPU, external 144Hz DP monitor on the dGPU. Symptoms (identical to this report): - shutdown completes, display turns off, but the machine never enters the final ACPI power-off state; fans/power stay on until holding the power button. - REBOOT works fine — only POWER OFF hangs. Since reboot and poweroff share device_shutdown(), the hang is in the poweroff-only ACPI S5 path (kernel_power_off_prepare → acpi_power_off). - NOT GPU-related: reproduced with both nouveau and the proprietary NVIDIA driver, and persists regardless of which GPU drives the display. Changes: upgraded from 6.17.0-29 to 7.0.0-28 on 2026-08-01/02 — poweroff broke immediately. Reverting to 6.17.0-29 (still installed) fixes it completely. Workaround that works: pin an older kernel (6.17.0-29 or 7.0.0-27) as the GRUB default until a fixed 7.0.x kernel ships (e.g. in GRUB: GRUB_DEFAULT="gnulinux-advanced-<uuid>>gnulinux-6.17.0-29-generic- advanced-<uuid>").
