after some debugging in #nm we found that there are two issues here: a) sierra modem goes down completely when sending CFUN=1 ... so we shouldnt do that.
b) crash of modemmanager when a tty disappears in the middle of activation. i will open a new bug for a) and adjust this bug title. ** Changed in: modemmanager (Ubuntu) Status: Incomplete => Triaged ** Changed in: modemmanager (Ubuntu) Assignee: (unassigned) => Alexander Sack (asac) ** Summary changed: - modem-manager crashed with SIGSEGV in dbus_connection_send() + modem-manager crashed when tty disappears during "enable" - with SIGSEGV in dbus_connection_send() ** Summary changed: - modem-manager crashed when tty disappears during "enable" - with SIGSEGV in dbus_connection_send() + MASTER - modem-manager crashed when tty disappears during "enable" - with SIGSEGV in dbus_connection_send() -- MASTER - modem-manager crashed when tty disappears during "enable" - with SIGSEGV in dbus_connection_send() https://bugs.launchpad.net/bugs/452427 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
