Morning...
I haven't enabled DDB in my kernel yet, but am curious...
I have a server setup with 3.0-current and the CAM drivers that is
periodically hanging on me (usually after a day or so of uptime)...that in
itself is annoying, but more annoying is that i have no way to resetting
that server, as it is 2500km away.
I do have a serial console configured on it, so that I can do
work, but I'm curious as to how I can break into DDB using the serial
console, without my home machine breaking into it also? On our Sparc
servers at work, you issue a ~# from a serial console to break down into
the boot prom...do we have something similar we can do?
