Hi,

I finished compiling X86 FS to utilize Ruby.
  scons -j 4 RUBY=True CPU_MODELS=TimingSimpleCPU  build/X86_FS/m5.fast

But Seg fault comes out if I use ruby_fs.py instead of fs.py.

1)
command line: build/X86_FS/m5.fast configs/example/ruby_fs.py -t
warning: add_child('terminal'): child 'terminal' already has parent
Global frequency set at 1000000000000 ticks per second
info: No kernel set for full system simulation. Assuming you know what you're doing...
Segmentation fault

2) after annotating kernel info explicitly.
For execution 2:
command line: build/X86_FS/m5.fast configs/example/ruby_fs.py -t --kernel x86_64-vmlinux-2.6.22.9
usage: ruby_fs.py [options]
ruby_fs.py: error: no such option: --kernel

yes, there is no code for handling the --kernel option in the ruby_fs.py different from fs.py.

Do you have any idea about it?

Thanks in advance.
