--- Comment #9 from Ernst Sjöstrand <ernstp@gmail.com> ---
(gdb) l *(amdgpu_fence_wait_empty+0x29)
0x112d9 is in amdgpu_fence_wait_empty
(drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c:270).
270             ptr = &ring->fence_drv.fences[seq &
ring->fence_drv.num_fences_mask];
(gdb) l *(amdgpu_fence_wait_empty+0x2a)
0x112da is in amdgpu_fence_wait_empty (./include/linux/compiler.h:243).
243             __READ_ONCE_SIZE;
(gdb) l *(amdgpu_fence_wait_empty+0x2b)
0x112db is in amdgpu_fence_wait_empty (./include/linux/compiler.h:243).
243             __READ_ONCE_SIZE;
(gdb) l *(amdgpu_fence_wait_empty+0x2c)
0x112dc is in amdgpu_fence_wait_empty (./include/linux/compiler.h:243).
243             __READ_ONCE_SIZE;
(gdb) l *(amdgpu_fence_wait_empty+0x2d)
0x112dd is in amdgpu_fence_wait_empty
(drivers/gpu/drm/amd/amdgpu/amdgpu_fence.c:273).
273             if (!fence || !dma_fence_get_rcu(fence)) {

It's not line 270 and not line 273 so I guess it's line 271 or 272:
        rcu_read_lock();
        fence = rcu_dereference(*ptr);
