Description

Original report: https://bbs.archlinux.org/viewtopic.php?id=241913

In drivers/gpu/drm/amd/amdgpu/gmc_v6_0.c, a MODULE_FIRMWARE entry for "amdgpu/hainan_mc.bin" is missing, but gmc_v6_0_init_microcode() tries to load it if chip_name is "hainan".

As a result, some initramfs generators fail to pick up the required firmware from the module metadata and do not include it in the generated image. During boot, amdgpu now fails to load the firmware.
