Hi All,

    Sometime dmesg show this log:

[10407.720988] [drm:amdgpu_ctx_mgr_entity_fini [amdgpu]] *ERROR* ctx 00000000189dec14 is still alive

[10407.721418] [drm:amdgpu_ctx_mgr_fini [amdgpu]] *ERROR* ctx 00000000189dec14 is still alive

What are the side effects?

Does this error will occur GPU hung(such as gfx timeout)?

How to fix this?

My kernel : 4.19.36

That is hopelessly outdated code, please try to switch something newer and re-test.

Christian.

Mesa: 18.3.6

And I find that in amdgpu_ctx.c, the function:amdgpu_ctx_mgr_entity_flush doesn't check the 

ctx->refcount(the check is stopped in this patch: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=48ad368a8a3ab2fd3c2bc2ccccc6e29b1acda1bb) , 

 why amdgpu_ctx_mgr_entity_fini still need check ctx->refcount?

Can i stop check ctx->refcount in  amdgpu_ctx_mgr_entity_fini ?

Thanks!
