I looked at src/mem/bus.cc -- there are two places it tries to access
peers which will segfault if there are none. I was able to get past
that particular segfault by guarding those statements with
if((*intIter)->isConnected()).
This appears to let the timing model run; but when I tried to run the
PARSEC benchmark I got another error with an atomic request being sent
to a ruby port:
command line: ./build/ALPHA/gem5.opt --remote-gdb-port=0
