> How can I debug the core dump file created by kernel panic? I try to use "gdb -core vmcore.0" (vmcore.0 is 4G file because I have 4G memory) and the gdb said: this is not a vaild core file. Why? AFAIK you have to use 'gdb -k' (or 'kgdb') to use GDB's kernel debugging mode. -- FreeBSD Volunteer, http://people.freebsd.org/~jkoshy
