Comment 26 for bug 126797

We still have this problem. It is especially apparent for us because we have 25 machines running folding that students use and sometimes reboot into Windows. Folding slows the logout process significantly, and during this time gdm comes back up and you can log in, however, the machine is still in the process of logging out and when it finishes roughly 90 seconds later it reboots, regardless of whether someone has logged in or not.

It seems to me the problem is caused by killing gdm on logout instead of stopping it.
