The new Debian 11/bullseye kernel 5.10.149-2 does not help on my setup. Still a black screen and nothing is logged. Also in rescue mode without "quiet".
My GPU is: 02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Tobago PRO [Radeon R7 360 / R9 360 OEM] (rev 81) 02:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Tobago HDMI Audio [Radeon R7 360 / R9 360 OEM] The GPU is running 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 My setup works flawless with linux-image-5.10.0-18-amd64.
