https://bugs.freedesktop.org/show_bug.cgi?id=109206 --- Comment #6 from Chris --- Still having the same bug in kernel 5.0-rc4 and my raven_dmcu.bin also matches to the previously attached bin file(sha256 a45972418d1c078afbd7884ffd58784954220759bc0d5464ce60165ffe1775bd). However, in one of my tests I got it to work! So the time it worked I got lucky I somehow misplaced raven_dmcu.bin so when I rebooted the kernel 5.0rc4 and checked /lib/firmware/amdgpu/raven_dmcu.bin it wasn't there. As soon as I put raven_dmcu.bin back in the folder /lib/firmware/amdgpu/ I got this bug again. So the workaround is to delete raven_dmcu.bin from /lib/firmware/amdgpu for now until they fix it. Laptop seems to work just fine. I don't know what that firmware is for but it doesn't look like it's a required file for my HP x360 AMD Ryzen 2500U laptop -- You are receiving this mail because: You are the assignee for the bug.
