Suspicious section from kernel 4.18.16 dmesg output: [ 2.801753] amdgpu 0000:09:00.0: Direct firmware load for amdgpu/polaris11_mc.bin failed with error -2 [ 2.801754] mc: Failed to load firmware "amdgpu/polaris11_mc.bin" [ 2.801852] [drm:gmc_v8_0_sw_init [amdgpu]] *ERROR* Failed to load mc firmware! [ 2.801936] [drm:amdgpu_device_init [amdgpu]] *ERROR* sw_init of IP block <gmc_v8_0> failed -2 [ 2.801999] amdgpu 0000:09:00.0: amdgpu_device_ip_init failed [ 2.802061] amdgpu 0000:09:00.0: Fatal error during GPU init [ 2.802117] [drm] amdgpu: finishing device. [ 2.802218] amdgpu: probe of 0000:09:00.0 failed with error -2
Error -2 is -ENOENT, "No such file or directory", so the amdgpu/polaris11_mc.bin file is missing where the amdgpu module is loaded from (could be the initrd). This is a configuration error, not a bug.
Thanks for your feedback! I'll communicate this back to Red Hat.
