Please compile with debug symbols ("makeoptions DEBUG=3D-g" in the =20
kernel config), generate a coredump and run kgdb on it. If you load =20
modules, you need to run "make gdbinit" in the kernel compile =20
directory (old style kernel compiling, not the make buildkernel one). =20
This will allow to run "kldsyms" in kgdb which loads the debug symbols =20
for the modules. A trace will show the line numbers then.
Bye,
Alexander.
