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?
