actually this is not a bug. I have found the solution to this problem. You just need to make sure that you have safely removes or eject all the removable drives (USB falsh disk, External Harddisk, etc) before shutting down. Because linux still reads it.
Mouse and external CD/DVD room doesn't have problems. This way the message ( linux name : xxx tty1 modemmanager(805): caught signal (15)) won't show up at all. So you don't need to edit conf, remove modemmanager or anything at all. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/869635 Title: long delay at shutdown/reboot - network-manager doesn't close correctly Status in “isc-dhcp” package in Ubuntu: Fix Released Status in “modemmanager” package in Ubuntu: Fix Released Status in “network-manager” package in Ubuntu: Fix Released Status in “wpasupplicant” package in Ubuntu: Fix Released Status in “isc-dhcp” source package in Oneiric: Confirmed Status in “modemmanager” source package in Oneiric: Confirmed Status in “network-manager” source package in Oneiric: Confirmed Status in “wpasupplicant” source package in Oneiric: Confirmed Bug description: I've noticed the shutdown and reboot in oneiric is slower than in natty.
