If we are trying to match Rocket w/ the configurations maybe this should be set to 8 by default (what Rocket does). IMO it's better to match Rocket then have a specific checkpointing config that has the right arch. state set than have some implicitly set default value that works for one config (Spike) but not for the other (Rocket) when reloading checkpoints.

Ok, it looks like this issue is something to do with SV39 v SV48. I'll just convert all configs to by default use SV39 again (instead of SV48) since SV39 was more thoroughly tested and it works with cospike. I'll update this PR to point to ucb-bar/testchipip#237
