Hi Yongbing Huang,
Are you sure you are restoring the same disk which you used to create the checkpoint? The error suggests that there is some inconsistency between the disk data, and how the system perceives the file system. I can imagine that this might happen when the CoW disk data in the checkpoint, or the information about the file system in the physmem is not from the same image as the image attached when restoring the checkpoint. >From which point are you restoring; is it in the middle of a boot sequence, or >does this error occur while running one of your added applications? What happens if you run a file system check on the image (e.g. e2fsck; you should be able to do this on your host system)? Could you please share a bit more information about what you are running (simulated system/gem5 command) and the output of both the gem5 simulator as the terminal when restoring the system from a checkpoint?

The error shows that "EXT2-fs (sda1): error: ext2_free_blocks: Freeing blocks not in datazone - block = 3856019482, count = 1". By the way, I run the simulator using the ARM platform, and modified the bbench disk image by adding more applications. However, the changes have already been written into the disk image before doing the checkpoint. So what may be the problem? Thanks. Best regards, Yongbing Huang
