Start the kernel with the -s parameter to get the symbols, and when in
the debugger, write down where it is (it tells you right above the db> line).

Then type in "trace" without the "", but with the return key at the end.

You get a procedure call list which led to the db. Note this to, then
tell us all of this, please.
