Comment 151 for bug 697095

#134 indicates that #6 is the reason for marking as wontfix and not open to SRU.

#6 just says that it happens on logout.

Actually, this is a particularly egregious and annoying bug.

It happens on shutdown too.

It means that a laptop will lock-up, and you need to forcibly power it off, and then wait for a fsck when next starting.

The condition for this bug to be triggered is:
 - install updates that require a reboot
 - perform the reboot via the menu
 - wait for machine to lock-up
