This seems to be the relevent error:

Calling udev_complete internally to avoid process lock-up." in the log. This looks like a problem we've discovered recently. See also: http://www.redhat.com/archives/dm-devel/2011-August/msg00075.html That happens when namespaces are in play. This was also found while using the Chrome web browser (which makes use of the namespaces for sandboxing). Do you use Chrome web browser?
