Hello! I am trying to use an AMD FirePro S7150X2 with the AMDGPU driver of a Linux 4.10.9 kernel (CoreOS Container Linux) and linux-firmware e39f0e3e6897ad865b3704f61218ae83f98a85da, but I run into the following error after the amdgpu module is being loaded: [ 17.692746] amdgpu 0000:84:00.0: enabling device (0000 -> 0003) [ 17.692940] [drm] initializing kernel modesetting (TONGA 0x1002:0x6929 0x1002:0x0334 0x00).
