Hello Ayaz and Everyone, I would like to run gdb tool within the image while restoring from the checkpoint in x86 O3CPU. I get a "segmentation fault error " when I restore from the checkpoint. The segmentation fault I get is in "system.pc.com_1.device" and simulation exits normally. I do not get any such error when I run on AtomicSimpleCPU or restore with AtomicSimpleCPU. I cannot use this method " http://www.gem5.org/Debugging_Simulated_Code";
