title: How to run a gem5 arm aarch64 full system simulation with fs.py with more than 8 cores?
body: <p>If I try to use more than <code>--num-cpus=8</code> cores, e.g. 16, 32 or 64, the terminal just stays blank.</p>
  
  <p>Tested with gem5 at commit 2a9573f5942b5416fb0570cf5cb6cdecba733392 and Linux kernel 4.16.</p>
