Hello,

how to solve this problem:

root@debian:/home/marko/
Downloads/gem5# ./build/X86/gem5.opt
configs/example/se.py -c ffmpeg -o "--file AVIDemo.avi"
gem5 Simulator System.  http://gem5.org

gem5 compiled Oct 19 2012 15:48:20
gem5 started Oct 22 2012 18:08:29
gem5 executing on debian
command line: ./build/X86/gem5.opt configs/example/se.py -c ffmpeg -o
--file AVIDemo.avi
Global frequency set at 1000000000000 ticks per second
0: system.remote_gdb.listener: listening for remote gdb #0 on port 7000
**** REAL SIMULATION ****

FATAL: kernel too old
panic: Tried to write unmapped address 0xffff_ffff_ffff_ffe8.

It seems like the address space is 64 bits and I am not sure if gem5 in SE mode support x86_64, does anyone know?

I believe the problem is that your physical machine is 64 bit. Try compiling your ffmpeg with the -m32 flag and re-run the simulation.
