I've found a regression in the 6.11 kernel, caused by the commit 3af2c80ae2 ("drm/amdgpu: refine gfx10 firmware loading"). On boot, the iGPU fails to initialize: [drm:amdgpu_device_init [amdgpu]] *ERROR* early_init of IP block <gfx_v10_0> failed -22 amdgpu: Fatal error during GPU init amdgpu: amdgpu: finishing device. Reverting the commit fixes the issue.
