Hi, The amdgpu driver from Linux 5.14 seems to require IOMMU support, which was disabled by default in my system's BIOS. My system (which has a Radeon RX 5700XT GPU) successfully booted 5.14 after enabling it in the BIOS. Previous 5.10 kernel also worked with IOMMU disabled. I did not do any further investigations.
In any case the missing firmware files from the original report are a red herring since the warnings either already existed for 5.10 kernel (e.g. the one about navi10_mes.bin) or are for quite recent GPUs, which were not yet supported by 5.10. Regards, -- Sebastian
