Bug Description

Binary package hint: network-manager

I'm using Ubuntu 9.04 Jaunty Jackalope UNR (Ubuntu Netbook Remix), with kernel linux-image-2.6.30-020630-generic from http://kernel.ubuntu.com/%7Ekernel-ppa/mainline/v2.6.30/ (however, I doubt the problem is kernel related as the hso module itself seems to behave correctly).

The Problem: When using an UMTS Connection via network-manager-gnome [Version: 0.7.1~rc4.1-0ubuntu2], shutting down the system hangs because the NetworkManager [Version: 0.7.1~rc4.1.cf199a964-0ubuntu2] process still claims /dev/ttyHS0.

Workaround: Killing NetworkManager and manually rmmod'ing the module hso remedies the situation and enables the system to shut down cleanly.

Expected Behaviour: NetworkManager should free /dev/ttyHS0 after termination of the connection or at latest after the UMTS device is removed, so that the hso module can be cleanly unloaded and doesn't block the shutdown.
