From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.0 (X11; Linux i686; U;) Gecko/20020326 Description of problem: When logging out of KDE via kicker menu, screen will occasionally go entirely black and reboot the system without the proper shutdown procedure (it simply reboots instantly). Version-Release number of selected component (if applicable): How reproducible: Sometimes Steps to Reproduce: 1. Log in to KDE 3 session 2. Log out and choose to save session. 3. Machine reboots without prompting or delay. Actual Results: Machine rebooted. Expected Results: Should have been returned to console prompt. Additional info: No error message whatsoever. Thank goodness for ext3!
Also, a non-root process (like KDE, unless you're using it as root which isn't recommended) can't reboot the machine. This is either an X or a kernel problem; can't tell which without being able to reproduce it. Do you get anything in /var/log/messages when this happens?
By any chance, are you using kdm and kdebase < 3.0.0-0.cvs20020321.1? If so, it's actually a kdm problem (misinterpreting the log out vs. reboot vs. shutdown choice in the logout dialog) and can be CLOSED:RAWHIDE.
Unable to find any traces or indications of problem in system logs. No longer occurs in skipjack-2 installation I am currently running. You can probably close this one out.
