BXT-P
Hardware 
Platform: Broxton P A0 Platform 
CPU Name : Intel(R) @ 1.2 GHz (family: 6, model: 92, stepping: 8) – 4 cores
SoC : BROXTON-P A0
CRB : Apollo Lake RVP Fab1
Software 
Linux distribution: Ubuntu 15.04 64 bits 
kernel 4.3.0-rc5 (26f82bd8) from https://github.com/ideak/linux.git BXT branch
commit 26f82bd872901733b739480e8899a92966ae9292
Author: Imre Deak <imre.deak@intel.com>
Date:   Tue Oct 20 16:44:03 2015 +0300
drm/i915/bxt: update bxt_defconfig
Enable Kconfig options needed for UART/eMMC.

Regression:
------------
No. Tested for the first time

Steps:
-------
1. Execute command:
./gem_reloc_vs_gpu

Actual result:
---------------
1. Most of the subtests are fail. IGT is not responding. Log shows a GPU hang.

Expected result:
----------------
1. Subtests are Pass

Cannot currently be reproduced on a newer kernel, on a BXT-P (LeafHill).
They are other problems with the test, and it hangs and timesout waiting for the GPU to reset.

Also confirm with last setup (kernel from nightly and also new Bios).
We will report the fail in another bug.
