--- Comment #6 from Jan Vesely <jv356 at scarletmail.rutgers.edu> ---
Can you post the output of 'clinfo'?
GPU hangs in clover are usually signs of old LLVM, or old mesa (that does not
catch function calls).

Do you use ocl-icd?
if yes can you confirm if the games hang when running with
OCL_ICD_VENDORS=/var/empty/ ?
(alternatively, you can just move libMesaOpenCL.* out of library path)

I doubt that. clover uses the same LLVM code generation paths.
also note: "the same problem with multiple games", I doubt those use OpenCL.
the above steps should confirm that.
My guess is that compute shaders are busted (irrespective of the API).
GPU reset has never worked correctly on any AMD GPU that I've ever used.
