Bug#692234: Intel HD 4000 (Ivy Bridge) graphics freeze

[Ingo <ingo.steiner@gmx.net>]

Seems this kernel has full support for Ivy Bridge and HD4000 grapkics
and H77 chipset compared to 3.2.0:

'cat /var/log/kern.log | grep RC6'
[drm:intel_enable_rc6], RC6 enabled
[drm:intel_enable_rc6], RC6 and deep RC6 enabled
[drm] Enabling RC6 states: RC6 on, RC6p on, RC6pp off
[drm:intel_enable_rc6], RC6 enabled


'dmesg | grep HDA'
input: HDA Digital PCBeep as /devices/pci0000:00/0000:00:1b.0/input/input7
