Dear Maintainer, System is a Lenovo Yoga 7 2-in-1 with an AMD Ryzen AI (Krackan Point, "Krackan2", PCI ID 1002:1902) integrated GPU. Fresh Debian 13 (Trixie) install. amdgpu driver loads but fails during GPU initialization at boot. Confirmed GPU is detected via lspci (Display controller: AMD/ATI Krackan2, rev c0). Confirmed amdgpu kernel module and firmware-amd-graphics (20250410-2, latest available in trixie/non-free-firmware) are installed and current. Manually updated amdgpu firmware from upstream linux-firmware git and rebuilt initramfs — no change. Added acpi_backlight=native kernel boot parameter — no change. dmesg shows: [ 3.474251] amdgpu 0000:04:00.0: amdgpu: Fatal error during GPU init [ 3.474310] amdgpu 0000:04:00.0: probe with driver amdgpu failed with error -22 No specific IP block failure is logged before this — it fails immediately after IP DISCOVERY (0x1002:0x1902 0x17AA:0x3829 0xC0) and MMIO register setup. Result: /sys/class/backlight is empty, /sys/class/drm has no card0 entry, /dev/dri/render* does not exist, xrandr reports gamma size 0. System has no working display driver at all — falls back to basic framebuffer console only. Expected a working amdgpu-driven display with functional backlight/brightness control, consistent with this hardware working correctly on Ubuntu with the same physical machine. -- System Information: Debian Release: 13.6 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 6.12.100+deb13-amd64 (SMP w/12 CPU threads; PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
