I see that issue was returned after this commit dd80d9c8eecac8c516da5b240d01a35660ba6cb6 is the first bad commit commit dd80d9c8eecac8c516da5b240d01a35660ba6cb6 Author: Christian König <christian.koenig@xxxxxxx> Date: Thu Jul 14 10:23:38 2022 +0200 drm/amdgpu: revert "partial revert "remove ctx->lock" v2" This reverts commit 94f4c4965e5513ba624488f4b601d6b385635aec. We found that the bo_list is missing a protection for its list entries. Since that is fixed now this workaround can be removed again.
