From: John Harrison <John.C.Harrison@xxxxxxxxx> It is technically possible to get a hung context without a valid request. In such a situation, try to provide as much information in the error capture as possible rather than just aborting and capturing nothing. Similarly, in the case of an engine reset failure the GuC is not able to report the guilty context. So try a manual search instead of reporting nothing.
