MM itself being respawned at reboot is unfortunate, but I really don't think it's blocking the system from rebooting. Fortunately, I happen to have a snowball board that I can test this with :)
Has it been verified that MM probing the device serial lines is really what is affecting the reboot? What this comes from is usually that MM dies somehow during the time the system is running, and then gets respawned by NetworkManager via DBus activation when it's discovered it's not running, shortly before NM is actually shut down by upstart. I think we largely fixed this with the upstart scripts in precise which have been slightly changed; but nothing will stop dbus activation to restart MM if it's found not to be running when NM checks its state. The stability was also improved in Precise (MM 0.5.2.0-0ubuntu2) It might be useful to try out with the modemmanager package from Precise, which you should be able to install without any issues on the Linaro 12.03 release, and see if the behavior has improved. OTOH, I'm absolutely for blacklisting the serial interfaces of the Snowball if I can get the vendor/product IDs and if we're sure they're not likely to ever be attached to a modem that MM should drive. Seems to me like that's pretty clear already. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/967174 Title: Reboot fails in Ubuntu To manage notifications about this bug go to: https://bugs.launchpad.net/igloocommunity/+bug/967174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
