Why doesnt loading a duplicate TR (not TC) work for you?  I've used that
method and found it to be reliable. 

Another way that is reliable (at least on our hardware) is to do a
load from a non-existent region 6 or 7 address. The failure modes are
different between region 6 & 7, but they both reliably produce MCAs.
