> panic: lockdebug_lookup: uninitialized lock (lock=0xffffffff80d01448, from=fff807bc16a) do you have the netbsd.gdb? can you look up fff807bc16a .. actually, that seems to be truncated. try 0xffffffff807bc16a. addr2line -e netbsd.gdb 0xffffffff807bc16a addr2line -e netbsd.gdb 0xffffffff80d01448 might both be useful.
