I compiled the kernel using config -g, then rebooted using that kernel. At some point, the system crashes, the dump file is written, and when it reboots, savecore saves the dump to the crash directory. The I use kgdb with this: ns11# kgdb /sys/i386/compile/ADKernel/kernel.debug /var/kcrash/vmcore.5 [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.
