Maybe... Might not be "consolekit" at all... I used "ssh" to login on my alpha this morning, and a simple "ps -ef" triggered the following (retrieved from the physical console when the "ps" hung):

Further attempts to generate a process listing resulted in more hung consoles, which meant the machine hung when I attempted a graceful reboot. Ultimately had to hit the reset switch :-(. Will try building 3.1.0-rc10 today and see if the problem recurs. --Bob -- To UNSUBSCRIBE, email to debian-alpha-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
