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.
