ACPI Error: [RAMB] Namespace lookup failure, AE_NOT_FOUND (20110112/psargs-359)
ACPI Exception: AE_NOT_FOUND, Could not execute arguments for [RAMW] (Region) (20110112/nsinit-349)

    Scope (_SB)
    {
        Name (RAMB, 0xDF5A1018)
        OperationRegion (\RAMW, SystemMemory, RAMB, 0x00010000)
    }

For above ASL code, we need to save scope node(\_SB) to lookup
the argument node(\_SB.RAMB).

ACPICA: Fix issues/fault with automatic "serialized" method support 2011-01-19T04:48:03+00:00 Lin Ming ming.m.lin@intel.com 2011-01-12T01:19:43+00:00 262948428878fb340127faca1791acb17146122e History: This support changes a method to "serialized" on the fly if the method generates an AE_ALREADY_EXISTS error, indicating the possibility that it cannot handle reentrancy. This fix repairs a couple of issues seen in the field, especially on machines with many cores. 1) Delete method children only upon the exit of the last thread, so as to not delete objects out from under running threads. 2) Set the "serialized" bit for the method only upon the exit of the last thread, so as to not cause deadlock when running threads attempt to exit. 3) Cleanup the use of the AML "MethodFlags" and internal method flags so that there is no longer any confustion between the two.
