What do you mean by checkpoint resumes properly? Are you able to connect
to the terminal and issue some commands? IIRC, there are two places in the
checkpoint where the PC and NPC are stored.

I'm using the AtomicSimpleCPU. Right for the _pc and _npc fields in the
checkpoint file I put zero, but the checkpoint still resumes properly. Here
are the first couple fetches:
1611728894411000: system.cpu: Fetch: PC:0x400880
1611728894412500: system.cpu: Fetch: PC:0x40056f
This happens every time I restore any checkpoint from this specific kernel
image.

Hey Guys,
I'm a little confused as to how exactly the checkpoint load works. I've
noticed that on a restore the PC is always at 0x400880. No matter what the
_pc is, M5 will always resume to that address, and then eventually get back
into normal execution. What is the exact code path the the simulator
follows when the "-r" flag is set?
That sounds really strange. What CPU model are you using?
