You might want to try the developer repository, although stable isn't
*that* out of date yet, and I'm pretty sure gem5 didn't behave this
way when stable was new. The fact that it stops very early suggests
that something is incrementally wrong. Are you sure your kernel file
is in the right place, has something in it, has the right permissions,
etc? You can try running with --debug-flags=Exec to see what it's
trying to do. There's also one I'm not remembering off hand which lets
you see memory access as they happen so you can see if, for instance,
all the fetches are coming back as zeroes. That may be "MemoryAccess"
or "MemoryAccesses" or something like that.
If you find that there was something wrong with your kernel file or
its permissions and gem5 didn't notice, please let us know so we can
put in some better error checking.

Hi all,
I am trying to run x86_FS mode but when I run:
build/X86_FS/m5.opt configs/example/fs.py
--kernel=/home/michael/gem5-stable/x86-system/binaries/x86_64-vmlinux-2.6.22.9
I get the following output:

I looked through the archives and couldn't find a solution to this
problem. I am running this on Ubuntu and using the gem5-stable
version. Any insight into why this is occuring and how to fix it
would be much appreciated.
Thank you,
Michael Borgens
