Do you add -G option? Yes. My dconschat works fine.

I only have kgdb, which needs a remote device (I use /dev/fwmem0.0, as in the docs). That doesn't work. # kgdb -r /dev/fwmem0.0 kernel.debug [kgdb copyright stuff] Switching to remote protocol get_tty_state failed: Invalid argument set_tty_state failed: Invalid argument get_tty_state failed: Invalid argument set_tty_state failed: Invalid argument Couldn't establish connection to remote target Reply contains invalid hex digit 12 kgdb> That leads me to my question as to whether this is a -current-only feature.
