You get this when you try to execute a non-memry instruction as a memory instruction.
You first need to figure out what type of instruction was being executed and then go about figuring what isn't done properly. Since you have a core dump you could view the stack trace most likely to figure out which instruction it was attempting to call initiateAcc() on. This will then give you some clue as to the name/type of instruction where this was called. Alternatively you could just run with "Exec" and "Decoder" debug flags turned on to see which instruction likely caused this (since it fails at cycle 34000, pretty fast). It may just be the case that its a memory instruction present in the ISA that gem5 currently doesn't have support for.
