Hi Ali, Thanks for the reply.
I have tried both 3.7 and 2.6 with those checks commented out. The simulator does not complain any more. However, I cannot see anything. Here is a trace: ./build/ARM/gem5.opt ./configs/example/fs.py warning: No header file specified for SimObject: Switch gem5 Simulator System. http://gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 compiled Jan 10 2013 13:07:30 gem5 started Jan 10 2013 13:09:52 gem5 executing on tianc-testBox command line: ./build/ARM/gem5.opt ./configs/example/fs.py Global frequency set at 1000000000000 ticks per second info: kernel located at: /home/tianc/Research/simulator/gem5/OS_images/tian-arm-system/binaries/vmlinux Listening for system connection on port 5900 Listening for system connection on port 3456 0: system.remote_gdb.listener: listening for remote gdb #0 on port 7000 info: Using bootloader at address 0x80000000 **** REAL SIMULATION **** info: Entering event queue @ 0.

Clearly, the linux does not boot or at least not boot to allow me to log in. I wonder if I did something wrong here. Linux kernel is compiled with 64-bit arm-linux-gnueabi-gcc on a 64-bit untuntu. Any suggestions? Thanks.
