Hi,
In the machine "shared_l2" configured in default.conf, If I change the L2
type from "L2_2M" to "L2_2M_mesi", the error happened. Both situation errors
may be caused by the same reason. But what reason?

Subject: [marss86-devel] Error running marss86 with three level cache
Hi,
I wrote a three level cache configuration, and run it with simple
operations such as "ls". Then I met the following error. Can anybody give some
advices?
