(In reply to CthUlhUzzz from comment #0) > "radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 > amdgpu.cik_support=1". FWIW, you only need radeon.si_support=0 amdgpu.si_support=1, since Oland is from the SI family. > [ 592.579114] amdgpu 0000:01:00.0: Direct firmware load for > radeon/oland_mc.bin failed with error -2 > [ 592.579124] amdgpu 0000:01:00.0: si_mc: Failed to load firmware > "radeon/oland_mc.bin" > [ 592.579133] amdgpu 0000:01:00.0: Failed to load mc firmware! The oland_mc.bin microcode is required. Make sure the package firmware-amd-graphics / firmware-linux-nonfree is installed, and maybe try re-generating the initrd.
