--- Comment #1 from yann <yann.argotti at intel.com> ---
There are improvements pushed in kernel and Mesa that will benefit to your
system, so please re-test with latest kernel & Mesa to see if this issue is
still occurring (you may update / upgrade to a more recent version of Fedora).

In the meantime, assigning to Mesa product (please let me know if I am mistaken
with this GPU Hang).

>From this error dump, hung is happening in render ring batch with active head
at 0x7c79f140, with 0x7a000003 (PIPE_CONTROL) as IPEHR.
