When I doing shutdown , my laptop freezing after the next lines: Network-manager: Caught signal 15 umount /run/lock is not mounted

Into /run/lock I can found ttyUSB0 file. What I can do in this situation?

Also I should add that ttyUSB0 - this is my 3G modem.

One more addition: I solve this problem by using hibernate. But really this can't solve my problem fully. So what is the difference between shut down and hibernate (I mean only stopping network manager). –  Lesya Makhova Feb 16 '12 at 7:38

type ls -l /var

Tell me if their are symbolic links set up on the directory "run" and the directory "lock" There needs to be symbolic links from /run to /var/run and /run/lock to /var/run/lock If there is not type the following commands:

sudo ln -s /run /var/run sudo ln -s /run/lock /var/lock

ls -l /var can find that links: lrwxrwxrwx 1 root root 9 2012-02-15 15:40 lock -> /run/lock lrwxrwxrwx 1 root root 4 2012-02-15 15:40 run -> /run –  Lesya Makhova Feb 16 '12 at 5:30
