--- Comment #15 from Michel Dänzer (michel@daenzer.net) --- (In reply to Dominic Letz from comment #14)
Having the same issue on an E495 with Kernel 5.12.9. Will try to downgrade the /lib/firmware/amdgpu any hint to which git tag you would consider safe?
20210315 seems to work fine here (on an E595).
