Can you add to the PR description something that states what we were capable of before and after the changes?

As I see that we were in fact able to backtrace to `kernel`panic` both before and after, but that after we have a few frames before that, and frames like ``kernel`kdb_sysctl_panic`` have argument values now.

So this is an improvement but I wonder how we were able to backtrace as much as we did without these changes. Maybe it's that we had return addresses to know what functions we came through, but the variables would have been incorrect if you inspected them.
