See the Kernel Debugging section of the > FreeBSD handbook for instructions on how to obtain such information. ddb did not help much: after the two 'kernel trap 12 with interrupts disabled' messages, the hot key does not work anymore. Using gdb on rpc.lockd and some ddb single-stepping, I was able to see that the freeze occurs somewhere during the first call to callrpc(). I'll try a remote GDB session and see if it helps to at least find out where precisely the error occurs. Or maybe I could add a call to panic() when the faulty trap occurs, which would drop me into DDB?
