Hehe, I've seen your emails on the subject in the archive ;-) > I'm planning to add an option to ddb where you can specify the dump > device at the time where you want to take the dump. Looks like a good idea. > Marco, where exactly is it panicing? Do you have ddb in the kernel? Yes, I have ddb in the kernel, although I am not good at it (I prefer symbolic debuggers ;-). It is panicing in the initialization of the routing tables, probably because I am playing with them :-) Anyway, reading the email archives I found a suggestion by bde (I think) who said: who needs a core dump, if you can use remote gdb? Well, since I have two machines, I found that remote gdb is the way to go :-) Thanks Marco -- Marco Molteni "rough consensus and running code" SRI International, System Design Laboratory To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
