>Description:
Since an update to RELENG_7 as of 2008/02/28
now I'm getting an error message in kgdb:
There is no member named pathname.

Also I'm unable to use the new add-kld command.

I tried to add an absent .symbols data manually
as I did before, but that doesn't work for me anymore.

p.s. It works for me in CURRENT though.
>How-To-Repeat:
# kgdb -q /boot/kernel/kernel /dev/mem
[GDB will not be able to debug user-mode threads:
/usr/lib/libthread_db.so: Undefined symbol "ps_pglobal_lookup"]
There is no member named pathname.
(kgdb) add-kld whatever
Undefined command: "add-kld".  Try "help".
