Unless you're using the KVM CPU or human input (neither should be true for regressions), gem5 is supposed to be entirely deterministic. If you're worried about last nights regressions, the x86 problem was because I pushed a CPUID related change but hadn't generated a stats CL to go with it. While I was doing so the regressions ran. It should be ok tonight.
