No. A debugging kernel isn't just a regular kernel with symbols. It
also adds many more runtime assertions. The symbols from one won't
match up with the core from another.

There's never a bad time to learn GDB! It'll still work even on your
non-debug kernel. You should try it out, and learn as much as you
can. When you feel like you've gone as far as you can by yourself,
then go ahead and post your problem to a mailing list of Bugzilla. Be
sure to post the full stack trace. And search for it on Bugzilla
before you post it; you may not be the first person to experience this
