--- Comment #10 from yann <yann.argotti at intel.com> ---
There were 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.

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