I just encountered the same thing. Blender crashed and brought down X (separate problem, will report). The screen was black. I couldn't switch to a tty. I pressed Ctrl-Alt-Delete and got the familiar "ding." Nothing happened. I was able to ssh in from another machine and found the following in a tail of /var/log/syslog:
Oct 1 15:51:12 localhost init: rc6 process (16981) killed by signal 15 Oct 1 15:51:12 localhost init: rc6 process (16996) killed by signal 15 Oct 1 15:51:12 localhost init: rc6 process (17012) killed by signal 15 Oct 1 15:51:12 localhost init: rc6 process (17066) killed by signal 15 Oct 1 15:51:12 localhost init: rc6 process (17075) killed by signal 15 Oct 1 15:51:12 localhost init: rc6 process (17095) killed by signal 15 Oct 1 15:51:12 localhost init: rc6 process (17111) killed by signal 15 Oct 1 15:51:12 localhost init: control-alt-delete respawning too fast, stopped Oct 1 15:51:16 localhost last message repeated 130 times Oct 1 15:51:17 localhost init: rc6 process (17228) killed by signal 15 Running sudo shutdown -r now completed successfully and displayed the message about the system going. Nothing happened, and there were no further messages to syslog. I was finally able to bring the system down with: sudo telinit 0 What else do you need, in terms of files/hardware specs/etc., to track this down? I'm running Edgy, all updated as of today. -- reboot sometimes doesn't https://launchpad.net/bugs/61431 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
