ACPI Error: Could not map memory at 0x000000007D422720, size 141
(20100702/exregion-178)
ACPI Exception: AE_NO_MEMORY, Returned by Handler for [SystemMemory]
(20100702/evregion-474)
ACPI Error (psparse-0537): Method parse/execution failed [\_PR_.CPU1.APCT]
(Node f70316c0), AE_NO_MEMORY



It's doing a dynamic table load:

Method (APCT, 0, NotSerialized)
{
    If (LAnd (And (CFGD, 0xF0), LNot (And (SDTL, 0x20
        ))))
    {
        Or (SDTL, 0x20, SDTL)
        OperationRegion (CST1, SystemMemory, DerefOf (Index (SSDT, 0x0A)),
           DerefOf (Index (SSDT, 0x0B)))
        Load (CST1, HC1)
    }
}


        Name (SSDT, Package (0x0C)
        {
            "CPU0IST ", 
            0x7D5B3520, 
            0x00000475, 
            "APIST   ", 
            0x7D368CA0, 
            0x000001CF, 
            "CPU0CST ", 
            0x7D398020, 
            0x00000C78, 
            "APCST   ", 
            0x7D422720, 
            0x0000008D
        })



Index 0x0A into the SSDT package is in fact 0x7D422720.

ACPI Error: Could not map memory at 0x000000007D422720, size 141

So, for whatever reason, the memory mapping failed.
