Hello, I am having trouble getting Linux to run on MacBook Pro 2019 with Radeon Pro Vega 20 4 GB. Basically as soon as graphical user interface starts, the whole system freezes. This happens with every Linux kernel version I have tried over the last few months, including 5.13. Using SSH I have been able to read dmesg output: [ 207.113144] [drm:amdgpu_dm_atomic_commit_tail [amdgpu]] *ERROR* Waiting for fences timed out! [ 207.113168] [drm:amdgpu_dm_atomic_commit_tail [amdgpu]] *ERROR* Waiting for fences timed out! [ 212.029866] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* ring gfx timeout, signaled seq=1022, emitted seq=1024 [ 212.030083] [drm:amdgpu_job_timedout [amdgpu]] *ERROR* Process information: process Xorg pid 918 thread Xorg:cs0 pid 919 [ 212.030276] amdgpu 0000:03:00.0: amdgpu: GPU reset begin! [ 216.030286] amdgpu 0000:03:00.0: amdgpu: failed to suspend display audio [ 227.396593] applesmc: driver init failed (ret=-5)! How do I debug this further?
