Hi, all:
How should I obtain the reason of kernel panic?
How should I debug the program which result in a kernel panic?
What can I get from the panic information?

Depends on the options your system has...(existence,size of dump...)
About the OS you say nothing...
My system is linux 3.0.4 on X86.

A crashed kernel writes no files... This is a safety feature preventing it from corrupting the disk.
Meaning, kernel panics don't get saved to disk, which is often unfortunate.
They usually get dumped to the raw VGA console. If you don't let your system start X11, you'll probably see them. You may need a digital camera or somesuch to capture the message since, as before, a crashed kernel writes no files.
You can also configure them to get sent to a serial port instead, I think, if your system has one, so a different machine or a serial printer can capture them.
