Hi all,

When I simulate a 4-core x86 system, my simulation always hangs during
system booting. And I tried to use hack_back_ckpt.rcS to create a
checkpoint but it doesn't work as well. The booting hangs at the step:

Fake M5 x86_64 CPU stepping 01
Brought up 4 CPUs

I use the below command to build the system
scons FULL_SYSTEM=1 build/X86/gem5.opt RUBY=True PROTOCOL=MOESI_hammer -j 4

The kernel I am using is x86_64-vmlinux-2.6.22.9.smp. And I use the run
command:
build/X86/gem5.opt -d m5out/cpt_general configs/example/fs.py --ruby -n 4
--script=configs/boot/hack_back_ckpt.rcS

Appreciate if anyone could shed some light!!

Regards,
Xin
