Reading the FAQ's is just the first step.

If it doesn't work at first try you will need to  analyze  and  debug
the problem. A few questions to get you started:

* You don't see any output - maybe there is  no  console  configured?
  Check  the  configuration of the serial console in your kernel, and
  try passing a suitable boot argument ("console=...").

* You think the kernel is hanging. Did you check there is any  useful
  information in the log_buf area? And yes, this is another FAQ - see

* If this doen't give any hints - did you attach a debuggger (BDI2000
  recommended) and check which state the kernel is in?

Best regards,
