Can I even do a dump if the ata driver is the culprit? 'trace' will give the backtrace, but I'm guessing what has happened is that part of init was being swapped out and failed, killing init, and hitting the panic in the exit syscall where it detects if init is the process exiting. No kernel dumps yet. 'man ddb' when the system is running normally will give a list of commands that can be issued to the debugger, as well as '?' at the prompt itself. About the only advice I can give is see if you can reproduce this each time with the xfce package build. That then allows some more debug to be put in. later, Peter.
