>Subject: [PATCH] tests/kms_flip: stop only ring when hanging the gpu
>
>Stopping all the rings will result multiple batches to hang.
>With multiple hangs from same context, the context gets banned
>and thus the gem_quietence_gpu will fail along with whole test.
>
>Fix this by stopping only one ring and thus the context
>gets blamed only once, allowing further gpu access.
