After bootloader i'm getting blackscreen
monitor outputing eqvivalent of no input message
i belive that this is being triggered on initialization of amdgpu since it's happening at the point where display usually changes the resolution and adding amdgpu.si_support=0 radeon.si_support=0
in kerneli cli allows me to boot and use GUI.
This is also happening on systemrescuecd with image that worked before on this system
This issue appeared suddenly while playing witcher2 after debian sandbox update
