hi gurus: how could i create the core dumps on freebsd kernel? i am trying to create a kernel core dump on 8.1 but it didn't happen: # sysctl -w debug.kdb.panic=1 well the system went panic, entered the mode db>. i did "reboot' but there was no core/kernel dumps under /var/crash. the customized kernel has those information enabled: # Debugging for use in -current options KDB # Enable kernel debugger support. options DDB # Support DDB. options GDB # Support remote GDB. user@host:~:$ sysctl -a | grep debug.kdb debug.kdb.stop_cpus: 1 debug.kdb.trap_code: 0 debug.kdb.trap: 0 debug.kdb.panic: 0 debug.kdb.enter: 0 debug.kdb.current: ddb debug.kdb.available: ddb by the way, where is my gdb? on one of my company's machisne, it looks like this: debug.kdb.available: ddb gdb thank you all /gahn
