Namespace dump from AcpiExec shows that the BKF1 field does not get created for some reason, needs investigation:

Interpreter currently cannot handle a TermArg as the 3rd parameter (BankValue):

BankField (R001, BNK1, Add (I001, Zero), ByteAcc, NoLock, Preserve)

Created an attachment (id=746) implement TermArg of BankField Op

Tested aginst ASLTS, no regression and error numbers drop down

And also tested the ASL code to check Termarg fix from http://xmas.sh.intel.com/linuxosbugzilla/attachment.cgi?id=507&action=view
