--- Comment #45 from Topi Pohjolainen <topi.pohjolainen at intel.com> ---
Dumping batches seems to change the runtime dynamics too much and the hang just
won't reoccur. I even tried a more light-weight version of batch dumping which
just checks that instruction is valid. Both require mapping and un-mapping of
the underlying buffer object which might prevent/hide the hang from reappearing
within reasonable amount time.
