Hello there, Problem solved. I did not set Cpu-Clock and Caches when I checkpoint the system, hence that’s why it throw the checkpoint in array. Now I can successfully load the new script file and got the output needed. Thanks.

I have no issue with Step 1, because that’s exactly what I did. I just have problem with Step 2 because although it can restore from the checkpoint, it can’t read the new script file.

In the other word, let checkpoing is created without any interaction. 2) Restore from checkpoint as usual. I though you may have problem with the step 1 Best, /T On 08/03/2018 01:14 PM, Woo L.L. wrote: Hi, I don’t think the script has any problem because as you can see from the result below, without any checkpointing, the program was able to execute till the end after booting.

However, with checkpointing, it seems to be stuck at trying to read a new script. I am not sure if I have missed any steps in between. I followed through the discussions about this issue – I didn’t connect my terminal during the 1st checkpointing, I view the result by tracing the terminal file. I didn’t make any changes to the hack_back_ckpt.rcS file. I also tried after loading the checkpoint and leaving the —script empty, I brought up the terminal to try and input the script file but only Ctrl+C made a difference. Anything other than that showed no difference. So, I am not sure where I have gone wrong. Appreciate all the help and guidance please. Thanks.
