I have only debugged the kernel in the old fashioned way myself, but gdb 
is able to attach itself to a running kernel. You can also patch the 
kernel with kdb (kernel debugger), that will help gdb to get out more 
useful info (and some serial console stuff it seems).

To debug after the crash is called "post mortem debugging", and a google 
search together with 'linux kernel' give some pointers to tools for 
doing that.
