title: Kernel freeze : How to debug it?
body: <p>I have an embedded board with a kernel module of thousands of lines which freeze on random and complexe use case with random time. What are the solution for me to try to debug it ?</p>
  
  <p>I have already try magic System Request but it does not work. I guess that the explanation is that I am in a loop or a deadlock in a code where hardware interrupt is disable ?</p>
  
  <p>Thanks,
  Eva.</p>
