--- Comment #2 from yann <yann.argotti at intel.com> ---
There are constant improvements pushed in kernel and Mesa that will benefit to
your system, so please re-test with latest kernel & Mesa (12 or 13) and mark as
REOPENED if you can reproduce (and attach fresh gpu error dump & kernel log)
and RESOLVED/* if you cannot reproduce.

In parallel, assigning to Mesa product.

Kernel: 4.8.11-1-ARCH
Platform: SKL (pci id: 0x1916, pci revision: 0x07, pci subsystem: 17aa:2238)
Mesa: [Please confirm your mesa version]

>From this error dump, hung is happening in render ring batch with active head
at 0xfe3de74c, with 0x7b000005 (3DPRIMITIVE) as IPEHR.
