--- Comment #2 from yann <yann.argotti at intel.com> ---
There were improvements pushed in kernel and Mesa (13)that will benefit to your
system, so please re-test with latest kernel & Mesa to see if this issue is
still occurring: mark as REOPENED if you can reproduce and RESOLVED/* if you
cannot reproduce.

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

Kernel: 4.4.0-rc6-mainline
Platform: Ivybridge (pci id: 0x0166, pci revision: 0x09, pci subsystem:
17aa:21fa)
Mesa: 12.0.4

>From this error dump, hung is happening in render ring batch with active head
at 0x00dcf294, with 0x7a000003 (PIPE_CONTROL) as IPEHR.

We can note also: ERROR: 0x00000101
    TLB page fault error (GTT entry not valid)
    Cacheline containing a PD was marked as invalid

and in render batch: Unloaded PD Fault (PPGTT)
