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]

From this error dump, hung is happening in render ring batch with active head at 0x7f903760, with 0x7a000003 (PIPE_CONTROL) as IPEHR.

We note also:
  ERROR: 0x00000105
    TLB page fault error (GTT entry not valid)
    Invalid page directory entry error

The problem hasn't reoccurred since I updated kernel and mesa.
