I'm using kgdb now, and I get the following error: $ kgdb -r /dev/cuaa0 kernel.debug [GDB will not be able to debug user-mode threads: /usr/lib/libthread_db.so: Undefined symbol "ps_pglobal_lookup"] GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.

The kernel.debug file is identical to the remote server however.
