--- Comment #1 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: 4.4.0-34-generic
Platform: IvyBrdige (pci id: 0x0166)
Mesa: [Please confirm your mesa version]

>From this error dump, hung is happening in render ring batch with active head
at 0x02dcf6ec, with 0x7a000003 (PIPE_CONTROL) as IPEHR.
