Hi Nilay,
As per your suggestion, I was trying to run the o3cpu with x86 in FS mode on
the latest dev repository. However I am still getting assertion failure. here
is the output:
command line: ./build/X86/gem5.opt configs/example/ruby_fs.py --num-cpus=2
--kernel x86_64-vmlinux-2.6.22.9.smp --cpu-type=detailed
warning: add_child('terminal'): child 'terminal' already has parent

I tried the timingcpu with the same kernel (I guess you compiled this kernel,
which we subsequently used for 757, Linux version 2.6.22
([email protected]) (gcc version 4.5.2 (GCC) ) #1 SMP Mon Feb 13
10:59:02 CST 2012) and it can bootup the cpu successfully.
Regards,
Dibakar
