from Pierre-Eric Pelloux-Prayer
Thanks for the bug report and the trace. I can reproduce the hang. There's always a page fault before, e.g: amdgpu 0000:0b:00.0: [gfxhub] page fault (src_id:0 ring:24 vmid:3 pasid:32772, for process glretrace pid 8616 thread glretrace:cs0 pid 8617) amdgpu 0000:0b:00.0: in page starting at address 0x0000000000f03000 from client 27 amdgpu 0000:0b:00.0: GCVM_L2_PROTECTION_FAULT_STATUS:0x00301031 amdgpu 0000:0b:00.0: MORE_FAULTS: 0x1 amdgpu 0000:0b:00.0: WALKER_ERROR: 0x0 amdgpu 0000:0b:00.0: PERMISSION_FAULTS: 0x3 amdgpu 0000:0b:00.0: MAPPING_ERROR: 0x0 amdgpu 0000:0b:00.0: RW: 0x0 I couldn't find the root cause yet.
