The one problem is when I get a hard hang, I do not get any error or panics. And there is no crash or dump data on reboot. Yes. I have enabled DDB and KDB and a dumpdir (in /etc/rc.conf) Am I missing something in the kernel debugging section? I see "11.9 Debugging Deadlocks" talk about Deadlocks. But at the time of the lock I have no way of doing a ps or really anything as the system is locked up solid. Roger
