possible fix

How about this one?  If it works, can you try adjusting the max_pipes_per_simd,
sx_num_of_sets, max_hw_contexts to see which combinations work?  E.g.,

v1:
rdev->config.cayman.max_pipes_per_simd = 2;
rdev->config.cayman.sx_num_of_sets = 2;
rdev->config.cayman.max_hw_contexts = 2;

v2:
rdev->config.cayman.max_pipes_per_simd = 4;
rdev->config.cayman.sx_num_of_sets = 2;
rdev->config.cayman.max_hw_contexts = 2;

v3:
rdev->config.cayman.max_pipes_per_simd = 2;
rdev->config.cayman.sx_num_of_sets = 4;
rdev->config.cayman.max_hw_contexts = 2;

v4:
rdev->config.cayman.max_pipes_per_simd = 2;
rdev->config.cayman.sx_num_of_sets = 2;
rdev->config.cayman.max_hw_contexts = 4;

v5:
rdev->config.cayman.max_pipes_per_simd = 4;
rdev->config.cayman.sx_num_of_sets = 4;
rdev->config.cayman.max_hw_contexts = 2;

v6:
rdev->config.cayman.max_pipes_per_simd = 2;
rdev->config.cayman.sx_num_of_sets = 4;
rdev->config.cayman.max_hw_contexts = 4;

v7:
rdev->config.cayman.max_pipes_per_simd = 4;
rdev->config.cayman.sx_num_of_sets = 2;
rdev->config.cayman.max_hw_contexts = 4;
