I'm open to suggestions. How can I force a core if ddb freezes? I have
tried 'sysctl debug.debugger_on_panic=0', but that doesn't help, just
causes me to have to hit the reset button for different reasons;
like an infinite loop worth of
kernel trap 12 with interupts disabled

True enough, but *what* I am debugging sure has changed. KLD for example
did not exist the last time I did kernel programming.
On the subject of which, I have a question regarding KLD, in my driver,
the MOD_LOAD does nothing,
the identify() does a BUS_ADD_CHILD() to the parent (nexus)
and then probe() and attach() do thier stuff and life is good.
Now I want to do a kldunload and have the driver dettach,
the MOD_UNLOAD is called, but the detach() is never called. What
do I need to do to get the detach() to be called? Is there an
opposite to BUS_ADD_CHILD()? I tried device_delete_child()... gave
me a panic and no core and devclass_delete_driver()... returned
an error (ENOENT, I think)
