Description From Bob Moore 2008-06-12 13:58:20

Bug detailed description:
--------------------------
The Unload operator does not fully delete the table. The namespace entries are
deleted, but the table remains in the global table data structure. If an
attempt is made to re-load the table, it will fail with AE_ALREADY_EXISTS.

Reproduce steps:
----------------
This ASL will not execute twice. Second execution fails with AE_ALREADY_EXISTS.

Method (OP)
{
    OperationRegion (OPR1, SystemMemory, ADDR, 0x2000)

    Load (OPR1, HNDL)
    Unload (HNDL)
}   







Current result:        
----------------


Expected result:    
----------------


Basic root-causing log:

Made the simple fix to detect that the table is still registered and allow the
load to continue.

In the future, we may have to fully delete the table, but for now this change
will suffice.
