Hi,
-current as of around "Mon Aug 26 18:39:00 CEST".
After booting the system up xdm didn't showed up and there was no
possibility to login on the console, so I breaked into ddb and send a
"kill 1" to xdm. Nothing happened so I again breaked into ddb and did a
"kill 1 1". Nothing happened again, so I decided to do a <ctrl>+<t>
(several times) -> boom.
