I am running Debian 11 with linux-image-5.10.0-19-amd64 and can confirm a similar problem with an AMD Radeon R7 360 on an Intel X58 board with Intel Xeon W3530 CPU and classic BIOS.
Kernel parameters are radeon.si_support=0 radeon.cik_support=0 amdgpu.si_support=1 amdgpu.cik_support=1 amdgpu.gpu_recovery=1
Nothing is logged and screen is black. No error messages at all. Works flawless with linux-image-5.10.0-18-amd64.
Kind regards,
Andreas
