Public bug reported:
Binary package hint: network-manager
Something in the NetworkManager / modem-manager conversation fails, and
NetworkManager crashes, leaving pppd running but the modem in a really
bad state, and the system very unstable.
Yeah, all the last is probably the kerne's fault (there's a bug for them
on that), but I'm rather frustrated so let me vent, OK? Ok.
So! Here's what I think is relevant from /var/log/syslog:

that line up there is the last line from NetworkManager.
Attached is the .crash file apport generated; unfortunately the system
hung shortly after and it seems the report is corrupted, so I'm not able
to process it with apport itself.
