Absolutely; I just set this up a few days ago, so I know this works with -CURRENT. First, set the sio.0.flags hint in /boot/device.hints to "0x90" so it is a vailable for use as a serial console. Then, set up the kernel with DDB and KDB and set /etc/sysctl.conf to turn the debug.debugger_on_panic switch to 1. You should probably be running with at least WITNESS and INVARIANTS, but not necessarily DIAGNOSTIC. -- Brian Fundakowski Feldman \'[ FreeBSD ]''''''''''\ <> green@FreeBSD.org \ The Power to Serve! \ Opinions expressed are my own. \,,,,,,,,,,,,,,,,,,,,,,\
