L2 cache on GPGPUSim cannot work

I’m working on the “GPGPUSim” simulator. I find that once the L2 cache is turned on, it cannot work normally. The simulation is always terminated by a deadlock. Anybody has run into this problem? What should I do to figure it? External Image

Use -gpgpu_L2_queue 32:32:32:32:32:32:0:0 then it should work.
