Hi, Thanks Bruse for the reply. I am running 3.3-Release of FreeBSD. And my kernel is elf kernel. So according to Bruce, I cannot set the breakpoints from DDB until sysinit() finishes. So what is the safe point from where I can set break points from DDB? I want to use DDB because I want to debug online. thanks for the help. --gb On Fri, 2 Jun 2000, Bruce Evans wrote: > On Thu, 1 Jun 2000, G.B.Naidu wrote: > > > I am having problems with DDB while setting breakpoints in the kernel.

Use gdb or set breakpoints early by value in broken versions. > > Bruce > -- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
