Hi, on an AMD Ryzen 5 PRO 4650U / Renoir (amdgpu: added device 1002:1636) I the screen basically freezes and I get the following errors with kernel v6.3-rc4 [ 26.214541] amdgpu 0000:03:00.0: [drm:amdgpu_ib_ring_tests [amdgpu]] *ERROR* IB test failed on gfx_low (-110). [ 26.379624] [drm] ring 0 timeout to preempt ib [ 27.387884] amdgpu 0000:03:00.0: [drm:amdgpu_ib_ring_tests [amdgpu]] *ERROR* IB test failed on gfx_high (-110). [ 27.392945] [drm:process_one_work] *ERROR* ib ring test failed (-110). [ 27.400370] amdgpu 0000:03:00.0: amdgpu: couldn't schedule ib on ring <gfx_low> [ 27.400384] [drm:amdgpu_job_run [amdgpu]] *ERROR* Error scheduling IBs (-22) [ 44.440532] amdgpu 0000:03:00.0: amdgpu: failed to write reg 28b4 wait reg 28c6 [ 61.177118] amdgpu 0000:03:00.0: amdgpu: failed to write reg 1a6f4 wait reg 1a706 [ 61.189275] amdgpu 0000:03:00.0: amdgpu: couldn't schedule ib on ring <gfx_low> [ 61.189286] [drm:amdgpu_job_run [amdgpu]] *ERROR* Error scheduling IBs (-22) I bisected the issue, the first bad commit is b589626674de94d977e81c99bf7905872b991197 reverting it on top of v6.3-rc4 also fixes the issue.
