Hi all, Checkpointing is not part of the regressions unfortunately, but is used heavily. Note though that most users of the checkpointing are running with atomic or KVM to drop the checkpoints, and resume with Minor or the O3CPU. Why are you taking checkpoints with the o3? (I’m not saying we shouldn’t fix it, it just doesn’t seem like the most urgent issue).

Taking checkpoints with arm_detailed CPU results in error from o3 cpu. I believe regression tests don't test for checkpoints (atleast the documentation here http://www.m5sim.org/Commit_Access says so). Is anyone else having this issue?
