--- Comment #3 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 parallel, assigning to Mesa product (please let me know if I am mistaken
with this GPU Hang).

Kernel: 4.2.3-300.fc23.x86_64
Platform: Haswell (pci id: 0x0416)
Mesa: [Please confirm your mesa version]
