Every thing was fine on previous kernel (5.9.12) but moving to 5.10.4 the amdgpu driver is failing with this error. Attached is full dmesg and lspci texts. Any idea was is causing this please ?

Looks like you have SME(Secure Memory Encryption) on and Raven will not work with SME. Please retry with "mem_encrypt=off"  kernel parameter.
