If you can place a serial console on the machine, and run commands from there. If that isn't possible make sure and run from console virtual terminal (ie not X) so that if there are kernel messages you can see them. The debugging sysrq-p and sysrq-t will show current state if machine isn't completely dead. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
