I have posted tar.gz files that include EthernetAll output (in ethernet_all.trace) @ http://rickshin.ucsd.edu. Once you have a chance, if you could take a look at the trace and figure what is wrong that is great.
I ended restoring from the checkpoint for two runs. One run stays in atomic mode while the other switches to timing and detailed. The run that stays in atomic mode works fine. This leads me to believe that the checkpoint restore mechanism is fine. The fault likely lies in the switching to timing or detailed mdoe. The differences between the runs: (1) m5out-atomic-run-aftercheckpoint.tar.gz is a run that stays in atomic mode (no switching to timing mode) (2) m5out-timing-run-aftercheckpoint.tar.gz is a run that switches to timing and then to detailed mode.
