Comment 152 for bug 211631

I still have a hang on reboot / shutdown even after installing the more recent netbase (4.45ubuntu3) and dbus (1.4.8-3ubuntu2) packages on my Kubuntu 11.04 laptop. I have four cifs shares defined in fstab. If I shutdown or reboot, I see network-manager caught signal 15, then a message about dbus, then modem-manager caught signal 15, then modem-manager restarts and load a bunch of plugins, then restarts again and again loads a bunch of plugins after several seconds' pause, and then the system hangs. If I unmount the network shares before shutting down / rebooting ("sudo umount - a"), the sequence is the same, except that after the second time modem-manager starts up, there's message about dbus that flashes briefly on the screen just before the power cycles off (so no hang if I unmount the network shares).
