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.
Signed-off-by: Imre Deak <imre.deak@intel.com>
BIOS: APLKRVPA.X64.0104.R43.1510080446 
BIOS (IFWI Version): APLK_IFWI_X64_R_2015_41_5_02
CSE : 3.0.0.1044
KSC : 1.02

Steps:
------
1. Boot DUT in text mode
2. Execute commands:
sudo -s
echo freeze > /sys/power/state
3. Press any key to resume
4. Check /var/log/kern.log

Actual results:
---------------
3. Suspend to freeze and resume work
4. Log contains some errors

Expected result:
----------------
4. No errors
