    Implement the fix for the erratum #712. - Processor May Hang During Graphics Memory Controller
    Sequencing
    
    The processor may hang during a graphics memory controller (GMC) sleep state transitioning. The failure may
    be processor specific and may be sensitive to temperature.
    
    Potential Effect on System:
    System hang.
    
    Suggested Workaround:
    BIOS should set D18F2x408_dct[1:0] bit 31 = 1b.
