Here's the command I run. My OS kernel is modified, but not in ways that
would matter. My gem5 version 21.0, not 21.2. My gcc is 10.3.0. I believe
my fs.py is out-of-the-box. You probably know this, but some of the arguments
on the command line are to gem5 and others are to fs.py. It's important to
get them in the right place (before / after fs.py on the command line).
I believe it looks for the checkpoint directory inside the --path directory.
./build/X86/gem5.fast --stats-file=stats_gem5.txt.gz
