Use the command like "kgdb /boot/kernel/kernel.symbols /dev/mem". Then, run the shell command ps -o pid,paddr | grep <pid> where pid is the pid of the hung process. Take the printed address A and, from kgdb, do: p *(struct proc *)A p/x *(((struct proc *)A)->p_threads.tqh_first) and show us the output. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
