Description of problem:
systemd sometimes crashes after resuming from suspend.  This removes the systemd message bus and nothing much works after that.  NetworkManager can't communicate so all the network interfaces show up as unmanaged.  I can't even shutdown properly, the laptop has to be hard booted.

I've seen this on both F18 and F19, different laptops.

Version-Release number of selected component:
systemd-201-2.fc18.8
