Hi. What commands would I have to run to reproduce this using unmodified gem5? Do you have any files I would need like the checkpoint file?
What seems to be happening is that in the new system, one of the devices (I can't tell which one) in your simulation isn't attached to anything, and it's upset about that. To start looking into it yourself, you could modify that panic to print the name of the device that port is associated with. All simobjects have a function called name() which (not surprisingly) returns their name. Once you know which device it is, you can look into why it's not getting hooked up when resuming from the checkpoint.
