I think that's right. Also, the panic is basically a segfault for the simulated program. It's complaining you tried to read from address 0x2 which doesn't correspond to anything in the process's address space. If you do find a specific bug (or implement a GPU!) please let us know. There's more information on debugging at http://www.m5sim.org/wiki/index.php/Debugging_M5
