Not closing modems when disconnected

[Noel J. Bergman]

Binary package hint: network-manager

NM 0.8, including the code upstream and in PPA, does not properly (tell Modem Manager to) close the serial device for a modem when disconnecting due to user action or system error. Modem Manager will therefore keep it open until Modem Manager closes.

Amongst other things, in current Karmic, this results in ttyACM0, 1, 2, 3, ... being created when the previous name is still in use due to not being closed.

Bug is confirmed and work is in progress to address it.

A preliminary patch has been committed upstream, and should be in the PPA tomorrow.

The part of this bug that related to hot-unplugging devices while still in use was fixed in modemmanager. It related to the kernel not generating udev remove notices for tty devices when the parent usb device of a tty device was removed, so modemmanager will now look for the usb removal of the parent as well.
