The BUG output in kern.log has disappeared now, but the problem (freeze on logout /shutdown) still remains. There are various people reporting this elsewhere, all marked as duplicates of #762203.
I have both an nvidia and an fglrx desktop machine displaying the bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/767927 Title: Logout Freeze [kernel tried to execute NX-protected page - exploit attempt?
