Hi Steve, Thanks for the quick response. I tried the m5 repository and ran into the same issue. I have attached the updated src/mem/bus.cc that we had in our old source. The changes that cause the problem are in calcPacketTiming, updating tickNextIdle and the packet firstWordTime and finishTime. Thanks, Joel
