A working example using > PAL_CACHE_WRITE would be nice. 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. -- Thanks Jack Steiner (651-683-5302) (vnet 233-5302) steiner@sgi.com
