System.map has these:
c0022910 t dump_instr
c0022a50 T __bad_xchg
c0022a88 t dump_backtrace <<----- offending
function
c0022ba0 T show_stack
c0022bbc T dump_stack
c0022bd8 T __div0
c0022bf8 T unregister_undef_hook
c0022c68 t dump_mem
c0022ddc T die
c0022fb8 T bad_mode
Probably dump_backtrace is not what I'm looking for :S
