Well I think I know what it is, but can't get the symbols to load.
When I load my kext, and do kextstat, the addresses begin there, so
that is must be where it is crashing within my NKE, but I try to
load my kext's symbol file generated by kextload -s, and do
backtrace(bt) and still it shows the ??,
Any ideas?

Hi,
I am getting this backtrace after loading the 10.3.5 symbol file, and
loading in my NKE symbol file,
but two lines are still undefined, any ideas on what could be causing
the panic??
Is it references way out of space memory address, because there is a
huge difference between the unknown and the known symbols.
Sorry not very good at debugging. Don't know where to get more info on
this, and what these 2 unknown lines could be.

Any help would be appreciated,
