> We can't do this technically as there are cases where we skip full device reset (even then amdgpu_in_reset will return true). The better thing to do is to move amdgpu_device_stop_pending_resets() later in

This sounds like it is a design issue then, if different reset workers expect different resets to be triggered but they all use the same flag. I wonder if the other places that check this flags are correct. FWIW I was testing with SRIOV where it always does full reset and ran into this issue.
