The kernel is a massive C program.
Download the source that matches your kernel and make yourself a set of tags
(ctags or gtags what ever you like).
When it blew up you should have some points in the stack with symbol names.
Walk through the call stack and look at the input and output of each
function with
the source in front of you.....
See where that (and a good search on the web) takes you....

If you made any source changes look for errors in your code ;-)
If you are running stock mainline code -- file a bug and if you find the source
of the bug first do an add to the report with what you think the error is.
