add-symbol-file

[Jerry Toung]

Hello list,
Could somebody tell me why I can't "list" the source code of this kld?
I built the module with COPTS=-g, it is loaded in the kernel and I run kgdb in 
/usr/obj/...../MYKERNEL. Everything seems to go well, except kgdb still 
doesn't like it. However if I run kldsyms, it only loads acpi.ko.debug and I 
can list it.
Thank you in advance,
Jerry

or 'trf portno' to connect to the remote target with the firewire
interface.  portno defaults to 5556.

Type 'getsyms' after connection to load kld symbols.

If you're debugging a local system, you can use 'kldsyms' instead
to load the kld symbols.  That's a less obnoxious interface.
